Swift Observatory's final act: a bright Andromeda portrait

NASA's Swift Observatory, which ended operations this week, took one of the best-ever photos of the Andromeda galaxy. The telescope captured millions of images during its mission, and scientists say this data could support astronomical discoveries for many years to come.

What cosmic object would you most want a retiring telescope to photograph?

Dying stars can glow pink or green, not just white

New observations show these stellar remnants can actually shine in a range of colors, including pink and green. Astronomers have found that a white dwarf's density and the type of material it has absorbed from its surroundings create different tints in its atmosphere.

What color do you imagine a star would turn as it slowly cools down?

James Webb Telescope hints at possible star collisions in early universe

A new look at the distant universe suggests star-on-star crashes may have been far more common billions of years ago. The James Webb Space Telescope has spotted extraordinarily compact stellar systems from not long after the Big Bang, a type of environment where such collisions become much more likely. In our own galactic neighborhood, space is so vast that stars rarely meet, but these tight clust…

🔭 Webb telescope peers into a stellar nursery 161,000 light-years away

If you look at the latest Picture of the Month from the James Webb Space Telescope, you are seeing dense clumps of gas where young stars are actively forming. The region, called LHA 120-N 159 (or N159), sits 161,000 light-years away in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The image spans about 230 light-years and reveals a turbulent cauldron of star birth. Why it matter…

Stellar activity may be making some mega-Earths look heavier than they are

A new study posted to arXiv suggests that stellar activity can mimic the signal of a much heavier planet. Some rocky planets reported to weigh more than 10 Earths may not be as massive as they appear, with their apparent heft being an illusion caused by the star's own activity. This matters because it challenges how we identify and characterize the most massive rocky planets.

What other ex…
