This illustration depicts a planet partially hidden in the glare of its host star and a nearby companion star. After examining a number of binary stars, astronomers have concluded that Earth-sized planets in many two-star systems might be going unnoticed by transit searches, which look for changes in the light […]

Diamond Light Source is the UK’s national synchotron (Image credit: Diamond Light Source) Electromagnetic (EM) radiation is incredibly useful. It enables us to transmit music wirelessly over large distances, cook food in the microwave and see the world in vivid detail. However, now more than ever, electromagnetic radiation is also crucial in […]

An artistic image inspired by a black hole-neutron star merger event. Credit: Carl Knox, OzGrav/Swinburne Mix pair is “elusive missing piece of the family picture of compact object mergers.” A long time ago, in two galaxies about 900 million light-years away, two black holes each gobbled up their neutron star […]

A report from the US task force dedicated to investigating UFOs — or, in the official jargon, UAPs (Unidentified Aerial Phenomena) — has neither confirmed nor rejected the idea such sightings could indicate alien visits to Earth. On Friday June 25, the Office of the Director of National Intelligence (ODNI) […]

To date, astronomers have confirmed the existence of 4,422 extrasolar planets in 3,280 star systems, with an additional 7,445 candidates awaiting confirmation. Of these, only a small fraction (165) have been terrestrial (aka. rocky) in nature and comparable in size to Earth – i.e., not “Super-Earths.” And even less have been found […]

This Hubble Space Telescope image offers a sampling of aging, red stars in the ultra-diffuse galaxy NGC 1052-DF2, or DF2. The galaxy continues to puzzle astronomers because it is lacking dark matter, an invisible form of matter that provides the gravitational glue to hold galaxies together. Precisely establishing the galaxy’s […]

ANIMATION UC Riverside-led study points to a seed black hole produced by a dark matter halo collapse. Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million […]

Artist’s illustration of an alien world.   ANIMATION Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems — within the small cosmic distance of 326 light-years — that could find Earth merely by watching our pale blue dot cross our sun. That’s 1,715 star-systems […]

A team led by UMD astronomers created the first clear image of an expanding bubble of stellar gas where stars are born using data from NASA’s SOFIA telescope on board a heavily modified 747 jet as seen here in this artist’s rendering. Credit: Artist Rendering by Marc Pound/UMD UMD-led team […]

Protoplanetary disks are classified into three main categories: transition, ring, or extended. These false-color images from the Atacama Large Millimeter/submillimeter Array (ALMA) show these classifications in stark contrast. On left: the ring disk of RU Lup is characterized by narrow gaps thought to be carved by giant planets with masses […]
