NASA's James Webb Space Telescope captured newborn stars forming in clouds of dust and gas (colored golden and orange in this image) in a star-forming region called Pismis 24.

"Sometimes it's the extreme objects that help us understand what's happening in the average ones."

Phases of ice that exist naturally only on frozen moons could be detected using infrared spectroscopy, according to new laboratory experiments.

The Perseverance has found compounds associated with life on Earth. But whether they indicate life on Mars awaits sample return.

The post Best Evidence Yet for Past Life on Mars? appeared first on Sky & Telescope.

The fourth satellite for the Copernicus Sentinel-1 mission, Sentinel-1D, has arrived at Félix Eboué airport, the main airport in French Guiana. From there the spacecraft, safely stored in its protective casing, will be transported to launch preparation facilities at the European Spaceport in Kourou.

The beams hint at the true scale of the massive star that spawned them.

"Capturing another satellite like this in an Earth-observation image is extremely rare."

A new study finds that one quarter of heat waves between 2000 and 2023 would have been “virtually impossible” without global warming—and can be attributed to the emissions of individual energy producers

Though NGC 7456 looks like a modest spiral galaxy, new Hubble and XMM-Newton observations reveal a bustling system with star-forming regions and an active core.

The European Space Agency’s Plato spacecraft has safely arrived at ESTEC, ESA’s technical heart in the Netherlands. There, engineers will complete the spacecraft by connecting its solar panels and sunshield, and carry out a series of critical tests to confirm that Plato is fit for launch and ready for its planet-hunting mission in space.

"The idea was for our payload to get us just up to the potential biosignature designation and have the rest of the story told by instruments here on Earth."
