Launched less than two months ago, ESA’s EarthCARE satellite has already returned images from two of its four instruments. Now, it has also delivered the first images from its multispectral imager, showcasing various types of clouds and cloud temperatures worldwide. This instrument is set to add valuable context to the data from EarthCARE’s other instruments.

Offering a foretaste of what’s to come once it is fully commissioned, ESA’s EarthCARE satellite has returned the first images from its broadband radiometer instrument. These initial images offer a tantalising glimpse into the intricacies of our planet’s energy balance – a delicate balance that governs our climate.

Supernova remnant 3C 58.X-ray: NASA/CXC/ICE-CSIC/A. Marino et al.; Optical: SDSS; Image Processing: NASA/CXC/SAO/J. Major The supernova remnant 3C 58 contains a spinning neutron star, known as PSR J0205+6449, at its center. Astronomers studied this neutron star and others like it to probe the nature of matter inside these very dense objects. A new study, made using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, reveals that the interiors of neutron stars may contain a type of ultra-dense matter not found anywhere else in the Universe.
In this image of 3C 58, low-energy X-rays are colored red, medium-energy X-rays are green, and the high-energy band of X-rays is shown in blue. The X-ray data have been combined with an optical image in yellow from the Digitized Sky Survey. The Chandra data show that the rapidly rotating neutron star (also known as a “pulsar”) at the center is surrounded by a torus of X-ray emission and a jet that extends for several light-years. The optical data shows stars in the field.
The team in this new study analyzed previously released data from neutron stars to determine the so-called equation of state. This refers to the basic properties of the neutron stars including the pressures and temperatures in different parts of their interiors.
The authors used machine learning, a type of artificial intelligence, to compare the data to different equations of state. Their results imply that a significant fraction of the equations of state — the ones that do not include the capability for rapid cooling at higher masses — can be ruled out.
The researchers capitalized on some neutron stars in the study being located in supernova remnants, including 3C 58. Since astronomers have age estimates of the supernova remnants, they also have the ages of the neutron stars that were created during the explosions that created both the remnants and the neutron stars. The astronomers found that the neutron star in 3C 58 and two others were much cooler than the rest of the neutron stars in the study.
The team thinks that part of the explanation for the rapid cooling is that these neutron stars are more massive than most of the rest. Because more massive neutron stars have more particles, special processes that cause neutron stars to cool more rapidly might be triggered.
One possibility for what is inside these neutron stars is a type of radioactive decay near their centers where neutrinos — low mass particles that easily travel through matter — carry away much of the energy and heat, causing rapid cooling.
Another possibility is that there are types of exotic matter found in the centers of these more rapidly cooling neutron stars.
The Nature Astronomy paper describing these results is available here. The authors of the paper are Alessio Marino (Institute of Space Sciences (ICE) in Barcelona, Spain), Clara Dehman (ICE), Konstantinos Kovlakas (ICE), Nanda Rea (ICE), J. A. Pons (University of Alicante in Spain), and Daniele Viganò (ICE).

Visual Description
This is an image of the leftovers from an exploded star called 3C 58, shown in X-ray and optical light. At the center of the remnant is a rapidly spinning neutron star, called a pulsar, that presents itself as a bright white object that’s somewhat elongated in shape.
Loops and swirls of material, in shades of blue and purple, extend outward from the neutron star in many directions, resembling the shape of an octopus and its arms.
Surrounding the octopus-like structure is a cloud of material in shades of red that is wider horizontally than it is vertically. A ribbon of purple material extends to the left edge of the red cloud, curling upward at its conclusion. Another purple ribbon extends to the right edge of the red cloud, though it is less defined than the one on the other side. Stars of many shapes and sizes dot the entire image.

NASA’s OSIRIS-REx mission has been immortalized at the Smithsonian’s National Air and Space Museum in Washington as the latest awardee of the Robert J. Collier Trophy. Bestowed annually by the National Aeronautic Association, the trophy recognizes groundbreaking aerospace achievements.
Members of the OSIRIS-REx team at the Smithsonian Institute’s National Air and Space Museum in Washington, D.C., with the Collier trophy on June 13, 2024. From left to right: Nayi Castro, mission operations manager, NASA’s Goddard Space Flight Center, Greenbelt, Md.; Nicole Lunning, curator, NASA’s Johnson Space Center, Houston; Anjani Polit, mission implementation systems engineer, University of Arizona, Tucson; Coralie Adam, OSIRIS-REx optical navigation lead, KinetX Inc.; Michael Moreau, OSIRIS-REx deputy project manager, NASA Goddard; Dennis Reuter, OVIRS instrument scientist, NASA Goddard; Ronald Mink, OSIRIS-REx missions systems engineer, NASA Goddard; Joshua Wood, system design lead, Lockheed Martin Space; Peter Antreasian, OSIRIS-REx navigation team chief, KinetX Inc.; Sandy Freund, program manager, Lockheed Martin Space; Eric Sahr, optical navigation engineer, KinetX Inc.NASA/Rani Gran OSIRIS-REx, formally the Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer, was honored “for successfully executing the first American retrieval of an asteroid sample and its return to Earth,” according to the award citation. The award was announced in March, and the OSIRIS-REx team visited the museum on June 13, 2024, to see the mission’s name engraved in brass at the base of the statue.
“It just blows me away to see the OSIRIS-REx team engraved on the Collier trophy, next to names like Orville Wright, the Apollo 8 crew, and the Voyager Mission Team,” said Michael Moreau, OSIRIS-REx deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “I’m so proud of our amazing team that their excellence and sacrifice to make the OSIRIS-REx mission so successful have been recognized with this prestigious award.”
While NASA’s accomplishments have been honored with the Collier award many times, this is one of just a handful of instances that NASA Goddard has been a major partner on a winning team. NASA Goddard most recently claimed a share of the award in 2022 for the James Webb Space Telescope. Previous wins also include 1993 honors for the Hubble Space Telescope and the 1974 prize for a NASA–U.S. Geological Survey satellite that began the long-running Landsat program that studies and monitors changes to Earth’s land masses.
The OSIRIS-REx team includes NASA’s Goddard Space Flight Center in Greenbelt, Maryland; Lockheed Martin in Littleton, Colorado; the University of Arizona, Tucson; and KinetX in Tempe, Arizona. NASA’s Johnson Space Center is responsible for the curation of the Bennu sample material that OSIRIS-REx returned to Earth in September 2023.
The Collier Trophy resides in a glass case in the “America by Air” section on the museum’s first floor. The century-old trophy stands at over 7 feet tall and weighs 525 pounds. The bronze sculpture depicts a globe, with three figures emerging from it. The sculpture rests on two walnut bases, each adorned with an engrave brass plaque bearing the names of the recipients.
Baltimore sculptor Ernest Wise Keyser designed the Trophy in 1910 for Robert J. Collier, the publisher of Collier’s Weekly magazine and president of the Aero Club of America.
