LEDA 1313424: The Bullseye Galaxy

'Temperamental' stars that brighten and dim over a matter of hours or days may be distorting our view of thousands of distant planets, suggests a new study.

IC 2574: Coddington's Nebula

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter in the cosmos. They are searching for dark matter using atomic clocks and cavity-stabilized lasers.

A new study focusing on Enceladus, a moon of Saturn, shows that the physics of alien oceans could prevent evidence of deep-sea life from reaching places where we can detect it.

Astronomers have characterized the largest-ever early-Universe radio jet. Historically, such large radio jets have remained elusive in the distant Universe. With these observations, astronomers have valuable new insights into when the first jets formed in the Universe and how they impacted the evolution of galaxies.

Where is Comet ATLAS going?

Earliest inner solar system planetesimals shaped the inventory of moderately volatile elements in terrestrial planets.

Yes, but can your rainbow do this?

Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to sense the gravitational tug or 'wobble' the planet induces on a star. Both the planet and brown dwarf are orbiting low-mass stars, a scenario thought to be extremely rare.

NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf galaxy -- shot through its heart. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using data from the W. M. Keck Observatory in Hawaii. Previous observations of other galaxies show a maximum of two or three rings.

Some stars explode in slow motion.

New research has combined cosmological data from two major surveys of the universe's evolutionary history and found hints that it may be less clumpy at certain points than previously thought. Their findings suggest that the universe may have become more complex with advancing age.

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the abundance of gamma rays in the universe.

Scientists found that asteroid Bennu contained a set of salty mineral deposits that formed in an exact sequence when a brine evaporated, leaving clues about the type of water that flowed billions of years ago.
