NASA Connects Little Red Dots with Chandra, Webb

A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A “X-ray dot” found by NASA’s Chandra X-ray Observatory could explain what the hundreds or potentially thousands of these objects are. A paper describing the […]

NASA’s Chandra Finds Young Stars Dim Quickly

These images, released on April 14, 2026, show two open star clusters, Trumpler 3 (left) and NGC 2353 (right). They represent a recent study from NASA’s Chandra X-ray Observatory that shows how young Sun-like stars are dimmer in X-rays than previously thought. This latest study looked at eight clusters of stars between the ages of […]

NASA Finds Young Stars Dim in X-rays Surprisingly Quickly

Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal.

NASA Discovers Crash of Extreme Stars in Unexpected Site

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before — and it may help solve two outstanding cosmic mysteries. A paper describing these results […]

Listen to This Month’s ‘Planetary Parade’ With NASA’s Chandra

In late February, people in the Northern Hemisphere can look up for a special sight: six planets will all be visible from clear and dark night skies. New sonifications from NASA’s Chandra X-ray Observatory released Feb. 25 will help commemorate this latest “planetary parade.” Because the planets in our solar system travel around the Sun […]

Young ‘Sun’ Caught Blowing Bubbles by NASA’s Chandra

For the first time, a much younger version of the Sun has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star. Winds from the star’s surface are blowing up the bubble and filling it with hot gas […]
