Scientists studying a mysterious signal from far-off galaxies didn't find dark matter as they'd hoped. But the inventive new technique they used to detect this strange signal, which... more
Observations of nearby galaxies and galaxy clusters have reported an unexpected x-ray emission line around 3.5 kilo–electron volts (keV). Proposals to explain... more
The winds and radiation blowing out of quasars — the most energetic objects in the universe — can kill star formation galaxy-wide, new research shows. more
Astronomers from Nanjing University in China have detected gamma ray emission from two star-forming galaxies designated M33 and Arp 299. The finding, which is detailed in a paper published March... more
The few thousand galaxies closest to us move in a vast 'bubble' that is 250 million light years in diameter, where the average density of matter is half as large... more
Quasars are the ultra-bright cores of distant active galaxies. These objects are among the most distant and luminous objects known. Their central engines are... more
This image taken by the NASA/ESA Hubble Space Telescope shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice's Hair), NGC 4237 is classified as a flocculent... more
In April 2019, the Event Horizon Telescope (EHT) Collaboration released stunning images of the supermassive black hole in Messier 87, a giant elliptical galaxy... more
About 85% of the matter in the universe is in the form of dark matter, whose nature remains a mystery, and the rest is of the kind found in atoms. Dark matter exhibits gravity but otherwise does not... more
A supernova in a nearby galaxy may have originated from an explosion of a blue supergiant formed by the merger of two stars, simulations by RIKEN astrophysicists suggest.... more
Image: This image shows a region of space called LHA 120-N150. It is a substructure of the gigantic Tarantula Nebula. The latter is the largest known stellar nursery in the... more
Researchers have designed a new camera that could allow hypertelescopes to image multiple stars at once. The enhanced telescope design holds the potential to obtain extremely... more

The Event Horizon Telescope image of the supermassive black hole in the galaxy M87 is dominated by a bright, unresolved ring. General relativity predicts that embedded within this image lies... more
New research raises the possibility that some parts of Mercury's subsurface, and those of similar planets in the galaxy, once could have been capable of fostering prebiotic chemistry, and perhaps... more
NASA has selected proposals for four missions that would study cosmic explosions and the debris they leave behind, as well as monitor how nearby stellar flares may affect... more
The subject of this image taken by the NASA/ESA Hubble Space Telescope, a spiral galaxy named NGC 1589, was once the scene of a violent bout of cosmic hunger pangs. As astronomers looked on, a poor, hapless star... more
Researchers have developed a technique to accurately measure the winding arms of spiral galaxies that is so easy, virtually anyone can participate. This new... more
Spiral structure is seen in a variety of natural objects, ranging from plants and animals to tropical cyclones and galaxies. Now researchers at the... more
Space research is an expensive business. Once a space-based instrument is proposed, researchers want to get as much value as possible from it. The proposed satellite quickly grows in instruments and capabilities.... more
Billions of lightyears away, gigantic clouds of hydrogen gas produce a special kind of radiation, a type of ultraviolet light known as Lyman-alpha emissions. The enormous clouds emitting the light... more
Astronomers using the Large Binocular Telescope have found a blazar 13 billion light-years from Earth, making it officially the most distant blazar ever detected.... more
Using data from various astronomical surveys, a team of researchers from China and India has investigated four poorly studied open clusters in our Milky Way galaxy. The new study, presented in a... more
Using the Large Area Telescope (LAT) onboard NASA's Fermi spacecraft, astronomers have investigated a nearby radio galaxy known as NGC 3894. Results of the study, presented in a paper published March 3, confirm the... more
The Earth, solar system, the entire Milky Way and the few thousand galaxies closest to us move in a vast "bubble" that is 250 million light years in diameter, where... more
Lyman-alpha blobs (LABs) are gigantic clouds of hydrogen gas that produce a special type of ultraviolet light known as Lyman-alpha emission. An extremely powerful energy source must produce this radiation, but scientists... more

A star that pulsates on just one side has been discovered in the Milky Way about 1500 light years from Earth. It is the first of its kind to be found and scientists expect to find... more
The barred spiral galaxy NGC 3887, seen here as viewed by the Wide Field Camera 3 aboard the NASA/ESA Hubble Space Telescope, lies over 60 million light-years away from us in the southern constellation of Crater... more
Using the United Kingdom Infrared Telescope (UKIRT) and NASA's Spitzer Space Telescope, astronomers have conducted photometric observations of a nearby star-forming galaxy known as NGC 6822.... more
A team of astronomers led by UC San Diego physicist Shelley Wright is deploying a pair of telescopes that will constantly search the nighttime sky for signals from intelligent life in our galaxy. more
Using the 6-meter telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences (SAO RAS), astronomers have conducted a detailed study of the central part of the galaxy... more
Data from ESA’s Gaia star-mapping satellite show that the warped disk of our Milky Way Galaxy precesses, or wobbles, similarly to the motion of... more
The galactic magnetic field plays an important role in the evolution of the galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the halo of the galaxy... more
Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with... more
