Webb’s infrared image highlights the planet’s dramatic rings and dynamic atmosphere. Following in the footsteps of the Neptune image released in 2022, the NASA/ESA/CSA James Webb Space Telescope has taken a stunning image of the solar system’s other ice giant, the planet Uranus. The new image features dramatic rings as well as bright features in the planet’s atmosphere.

The Webb data demonstrates the observatory’s unprecedented sensitivity for the faintest dusty rings, which have only ever been imaged by two other facilities: the Voyager 2 spacecraft as it flew past the planet in 1986, and the Keck Observatory with advanced adaptive optics.

The seventh planet from the Sun, Uranus is unique: it rotates on its side, at a nearly 90-degree angle from the plane of its orbit. This causes extreme seasons since the planet’s poles experience many years of constant sunlight followed by an equal number of years of complete darkness. (Uranus takes 84 years to orbit the Sun.) Currently, it is late spring for the northern pole, which is visible on the images of this article; Uranus’ northern summer will be in 2028. In contrast, when Voyager 2 visited Uranus it was summer at the south pole. The south pole is now on the ‘dark side’ of the planet, out of view and facing the darkness of space.

This infrared image from Webb’s Near-Infrared Camera (NIRCam) combines data from two filters at 1.4 and 3.0 microns, which are shown here in blue and orange, respectively. The planet displays a blue hue in the resulting representative-color image.

When Voyager 2 looked at Uranus, its camera showed an almost featureless blue-green ball in visible wavelengths. With the infrared wavelengths and extra sensitivity of Webb we see more detail, showing how dynamic the atmosphere of Uranus really is.

On the right side of the planet there’s an area of brightening at the pole facing the Sun, known as a polar cap. This polar cap is unique to Uranus – it seems to appear when the pole enters direct sunlight in the summer and vanishes in the fall; this Webb data will help scientists understand the currently mysterious mechanism. Webb revealed a surprising aspect of the polar cap: a subtle enhanced brightening at the center of the cap. The sensitivity and longer wavelengths of Webb’s NIRCam may be why we can see this enhanced Uranus polar feature when it has not been seen with other powerful telescopes like the NASA/ESA Hubble Space Telescope and NASA’s Keck Observatory.

At the edge of the polar cap lies a bright cloud as well as a few fainter extended features just beyond the cap’s edge, and a second very bright cloud is seen at the planet’s left limb. Such clouds are typical for Uranus in infrared wavelengths, and likely are connected to storm activity.

This planet is characterized as an ice giant due to the chemical make-up of its interior. Most of its mass is thought to be a hot, dense fluid of “icy” materials – water, methane and ammonia – above a small rocky core.

Uranus has 13 known rings and 11 of them are visible in this Webb image. Some of these rings are so bright with Webb that when they are close together, they appear to merge into a larger ring. Nine are classed as the main rings of the planet, and two are the fainter dusty rings (such as the diffuse zeta ring closest to the planet) that weren’t discovered until the 1986 flyby by Voyager 2. Scientists expect that future Webb images of Uranus will reveal the two faint outer rings that were discovered with Hubble during the 2007 ring-plane crossing.

Webb also captured many of Uranus’s 27 known moons (most of which are too small and faint to be seen here); the six brightest are identified in the wide-view image. This was only a short, 12-minute exposure image of Uranus with just two filters. It is just the tip of the iceberg of what Webb can do when observing this mysterious planet. Additional studies of Uranus are happening now, and more are planned in Webb’s first year of science operations.

More information Webb is the largest, most powerful telescope ever launched into space. Under an international collaboration agreement, ESA provided the telescope’s launch service, using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace. ESA also provided the workhorse spectrograph NIRSpec and 50% of the mid-infrared instrument MIRI, which was designed and built by a consortium of nationally funded European Institutes (The MIRI European Consortium) in partnership with JPL and the University of Arizona.

Webb is an international partnership between NASA, ESA and the Canadian Space Agency (CSA).

Wow, that's a wonderful view. To be honest, I'd bring a foldable chair and sit there all day if I could. There's nothing like listening to and watching the waves underneath a beautiful skyline. It must also be a nice and scenic drive going there. I don't know what I'd put on the stereo to prepare me for it, though. Maybe Schubert's Wind Quartet in B Moll Major from String Trio, D471, but something light.

 

In Congress, July 4, 1776

The unanimous Declaration of the thirteen united States of America, When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.

He has refused his Assent to Laws, the most wholesome and necessary for the public good.

He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.

He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.

He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public Records, for the sole purpose of fatiguing them into compliance with his measures.

He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.

He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.

He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands.

He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary powers.

He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries.

He has erected a multitude of New Offices, and sent hither swarms of Officers to harrass our people, and eat out their substance.

He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.

He has affected to render the Military independent of and superior to the Civil power.

He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation:

For Quartering large bodies of armed troops among us:

For protecting them, by a mock Trial, from punishment for any Murders which they should commit on the Inhabitants of these States:

For cutting off our Trade with all parts of the world:

For imposing Taxes on us without our Consent:

For depriving us in many cases, of the benefits of Trial by Jury:

For transporting us beyond Seas to be tried for pretended offences:

For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies:

For taking away our Charters, abolishing our most valuable Laws, and altering fundamentally the Forms of our Governments:

For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.

He has abdicated Government here, by declaring us out of his Protection and waging War against us.

He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people.

He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.

He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.

He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.

In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince, whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.

Nor have We been wanting in attentions to our Brittish brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.

We, therefore, the Representatives of the united States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good People of these Colonies, solemnly publish and declare, That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.

Well, the NIRCam is a Near-InfraRed Camera, so it wouldn't look like that in person.

 

With giant storms, powerful winds, aurorae, and extreme temperature and pressure conditions, Jupiter has a lot going on. Now, the NASA/ESA/CSA James Webb Space Telescope has captured new images of the planet. Webb’s Jupiter observations will give scientists even more clues to Jupiter’s inner life.

In this wide-field view, Webb sees Jupiter with its faint rings, which are a million times fainter than the planet, and two tiny moons called Amalthea and Adrastea. The fuzzy spots in the lower background are likely galaxies “photobombing” this Jovian view.

This is a composite image from Webb’s NIRCam instrument (two filters) and was acquired on 27 July 2022.

This is one of a series of images taken by the ESA/JAXA BepiColombo mission on 8 January 2025 as the spacecraft sped by for its sixth and final gravity assist manoeuvre at the planet. Flying over Mercury's north pole gave the spacecraft's monitoring camera 1 (M-CAM 1) a unique opportunity to peer down into the shadowy polar craters.

M-CAM 1 took this long-exposure photograph of Mercury's north pole at 07:07 CET, when the spacecraft was about 787 km from the planet’s surface. The spacecraft’s closest approach of 295 km took place on the planet's night side at 06:59 CET.

In this view, Mercury’s terminator, the boundary between day and night, divides the planet in two. Along the terminator, just to the left of the solar array, the sunlit rims of craters Prokofiev, Kandinsky, Tolkien and Gordimer can be seen, including some of their central peaks.

Because Mercury’s spin axis is almost exactly perpendicular to the planet's movement around the Sun, the rims of these craters cast permanent shadows on their floors. This makes these unlit craters some of the coldest places in the Solar System, despite Mercury being the closest planet to the Sun!

Excitingly, there is already evidence that these dark craters contain frozen water. Whether there is really water on Mercury is one of the key mysteries that BepiColombo will investigate once it's in orbit around the planet.

The left of the image shows the vast volcanic plains known as Borealis Planitia. These are Mercury’s largest expanse of ‘smooth plains' and were formed by the widespread eruption of runny lava 3.7 billion years ago.

This lava flooded existing craters, as is clearly visible in the lower left Henri and Lismer craters. The ‘wrinkles’ seen in the centre-left were formed over billions of years following the solidification of the lava, probably in response to global contraction as Mercury’s interior cooled down.

The volume of lava making up Borealis Planitia is similar in scale to mass extinction-level volcanic events recorded in Earth’s history, notably the mass extinction event at the end of the Permian period 252 million years ago.

The foreground of the image shows BepiColombo's solar array (centre right), and a part of the Mercury Transfer Module (lower left).

[Technical details: This image of Mercury's surface was taken by M-CAM 1 on board the Mercury Transfer Module (part of the BepiColombo spacecraft), using an integration time of 40 milliseconds. Taken from around 787 km, the surface resolution in this photograph is around 730 m/pixel.]

The People’s Forum and Code Pink may be obligated to register as foreign agents due to Chinese Government funding and influence

BUTLER COUNTY, IOWA – Senate Judiciary Committee Chairman Chuck Grassley (R-Iowa) is urging the Department of Justice (DOJ) to assess whether The People’s Forum and Code Pink are obligated to register under the Foreign Agents Registration Act (FARA), due to the group’s reported Chinese Communist Party ties.

“Evidence suggests that The People’s Forum and Code Pink have been funded and influenced by Mr. [Neville Roy] Singham and the communist Chinese government, both of which are foreign principals. The evidence also suggests that The People’s Forum and Code Pink have engaged in covered political activities that directly advance the communist Chinese government’s political and policy interests,” Grassley wrote.

“Secretive foreign lobbying and public relations campaigns by China and other adversaries undermines the political will and interests of the American people. The People’s Forum and Code Pink’s reported role in advancing policies in favor of the communist Chinese government is more than alarming and their potential obligation to register as foreign agents for purposes of FARA ought to be investigated,” Grassley continued.

Read Grassley’s letter to Attorney General Pam Bondi and Federal Bureau of Investigation (FBI) Director Kash Patel HERE.

Background:

Neville Roy Singham is a social activist and billionaire who reportedly “works closely with the Chinese government media machine and is financing its propaganda worldwide.” Singham has reportedly attended Communist Party workshops focused on “promoting the party internationally,” shares office space and staff with the Shanghai Maku Cultural Communication Company and co-produces a YouTube show that’s partially financed by China’s propaganda department.

The People’s Forum, self-described as a “political and cultural hub,” is also funded in large part by Singham – who reportedly donated over $20.4 million through a series of shell organizations and donor advisory groups. The People’s Forum offers courses titled, “Lenin and the Path to Revolution” and “China75 – When the People Stand Up.” The group joined Code Pink in hosting a conference moderated by the Qiao Collective, known as “a diaspora Chinese media collective.” Further, the Executive Director of the People’s Forum openly pedaled Chinese propaganda when appearing on CGTN, a Chinese state-owned media group. DOJ directed CGTN to register under FARA in 2019.

Code Pink, self-described as a “grassroots organization working to end U.S. warfare and imperialism,” was founded by Singham’s wife, Jodie Evans, and has reportedly received roughly a quarter of its donations from organizations with ties to Singham. Since marrying Singham in 2017, Evans and Code Pink have “stridently support[ed] China,” with Evans publicly describing the Uyghurs, an ethnically Muslim minority group, as “terrorists” and defending their mass detention. Further, Code Pink activists have met with the House Select Committee on China to directly advocate for Chinese interests, including denying evidence of forced labor in the Uyghurs’ native region of Xinjiang.
