Students digging into data archive spot mysterious X-ray source
An enigmatic X-ray source revealed as part of a data-mining project for high-school students shows unexplored avenues hidden in the vast archive of ESA's XMM-Newton X-ray Observatory.
First coronal mass ejection from a star other than the sun observed
Omega Centauri unlikely to harbor life
Searching for life in the vast universe is an overwhelming task, but scientists can cross one place off their list.
Impact of a stellar intruder on our solar system
The solar system was formed from a protoplanetary disk consisting of gas and dust. Since the cumulative mass of all objects beyond Neptune is much smaller than expected and the bodies there mostly have inclined, eccentric ...
Pairs of small colliding galaxies may seed future stars
A pair of dwarf galaxies closely circling the Milky Way, the Large and Small Magellanic Clouds, were in the throes of merging into one when they fell into our galaxy. The duo is thought to hold enough gas to replenish half ...
Astrophysicists discover that ultrahot planets have starlike atmospheres
Recent observations by NASA's Hubble and Spitzer space telescopes of ultrahot Jupiter-like planets have perplexed theorists. The spectra of these planets have suggested they have exotic—and improbable—compositions.
Finding the happy medium of black holes
This image shows data from a massive observing campaign that includes NASA's Chandra X-ray Observatory. These Chandra data have provided strong evidence for the existence of so-called intermediate-mass black holes (IMBHs). ...
The Umov Effect—space dust clouds and the mysteries of the universe
FEFU scientists are developing a methodology to calculate the ratio of dust and gas in comas and tails of comets. This will reveal more about the history of the solar system and its development, as well as to understand the ...
Astronomers report the most distant radio galaxy ever discovered
After nearly 20 years, the record of the most distant radio galaxy ever discovered has been broken. A team led by Ph.D. student Aayush Saxena (Leiden Observatory, the Netherlands) has found a radio galaxy from a time when ...
