Looking for “wobbling” stars is a useful way to detect exoplanets, but stellar noise prevents us from reaching the precision needed to find Earth-twin planets. The key to solving this problem may be to examine our own star.
The recent discovery of 158 previously undetected dwarf galaxies in the Fornax cluster may help to solve a long-standing puzzle in galaxy formation and evolution.
Spitzer has recently taken beautiful infrared images of 2352 nearby galaxies, as a part of the Spitzer Survey of Stellar Structure in Galaxies (S4G).
In June of this year, the black hole V404 Cygni woke up after nearly three decades of sleep. Now we’re getting the first descriptions of what we’ve learned from its awakening!
Recent analysis of a powerful solar outburst — captured on video by several Sun-monitoring spacecraft — may help us to understand how it was launched.
The surface of comet 67P Churyumov–Gerasimenko is covered in active pits — some measuring hundreds of meters both wide and deep! But what processes caused these pits to form?
The subgiant and white dwarf of the Procyon binary system orbit each other with a tiny angular separation, creating a distinct challenge for astronomers to observe. Two decades of Hubble observations have now finally revealed some of its secrets.
Who needs humans? Robotic observations have been used to measure the mass of a supermassive black hole at the center of an active galaxy.
A new study has discovered a population of very young stars in a thin disk through the galactic center, providing clues to the star formation history of the Milky Way over the last 100 million years.
Dual active galactic nuclei are often produced when two galaxies collide, but they’re difficult to identify because the nuclei are so close together. Now, a team of authors has found a new way of confirming these objects.
The T Tauri star PTFO 8-8695 has been suspected of harboring a close-in giant planet, but a recent study has cast doubt on this theory.
A recent study used the Hubble Space Telescope to perform a high-resolution multi-band survey of Westerland 2, the very young star cluster visible in this spectacular image.
