How Stars Form in the Smallest Galaxies

The question of how small, dwarf galaxies have sustained the formation of new stars over the course of the Universe has long confounded the world's astronomers. An international research team has ...

Extremely Young Galaxy Is Milky Way Look-Alike

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The galaxy is ...

Surprising Early Galaxy Breaks Low-Oxygen Record

New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% solar abundance, ...

Strange Dismembered Star Cluster Found at Galaxy's Edge

Astronomers have found the remnant of strange dismembered globular cluster at the edge of the Milky Way, upending theories about how heavy elements formed in early ...

New Research Hints at the Presence of Unconventional Galaxies Containing 2 Black Holes

Astronomers have identified periodic gamma-ray emissions from 11 active galaxies, paving the way for future studies of unconventional galaxies that might harbor two supermassive black holes at their ...

Quasar Jets Are Particle Accelerators Thousands of Light-Years Long

An international collaboration bringing together over 200 scientists from 13 countries has shown that the very high-energy gamma-ray emission from quasars is not concentrated in the region close to ...

A team of astronomers has picked up on a curious, repeating rhythm of fast radio bursts emanating from an unknown source outside our galaxy, 500 million light years ...

Is there anyone out there? This is an age-old question that researchers have now shed new light on with a study that calculates there could be more than 30 intelligent civilizations throughout our ...

Using AI to Unlock Clues to the Origins of the Stars and Planets

An artificial intelligence (AI) system analysing data from the Gaia space telescope has identified more than 2,000 large protostars, young stars that are still forming and could hold clues to the ...

Hubble Makes Surprising Find in the Early Universe

New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought. A European team of ...

First Optical Measurements of Milky Way's Fermi Bubbles Probe Their Origin

Astronomers have for the first time measured the Fermi Bubbles in the visible light spectrum. The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the ...

Ultra-Bright X-Ray Source Awakens Near a Galaxy Not So Far Away

A new ultra-bright source of X-rays has awakened in between our galactic neighbors the Magellanic Clouds, after a 26-year slumber. This is the second-closest such object known to date, with a ...

Large Simulation Finds New Origin of Supermassive Black Holes

Computer simulations conducted by astrophysicists have revealed a new theory for the origin of supermassive black holes. In this theory, the precursors of supermassive black holes grow by swallowing ...

Asymmetry Found in Spin Directions of Galaxies

The patterns formed by spiral galaxies show that the universe may have a defined structure and suggest that the early universe could have been spinning, according to a computational ...

The Milky Way Has One Very Hot Halo, Astronomers Find

The halo that surrounds our own Milky Way galaxy is much hotter than scientists once believed - and it may not be unique among ...

Under Pressure, Black Holes Feast

A new study shows that some supermassive black holes actually thrive under pressure. It has been known for some time that when distant galaxies -- and the supermassive black holes within their cores ...

Astronomers Discover New Class of Cosmic Explosions

Analysis of two cosmic explosions indicates to astronomers that the pair, along with a puzzling blast from 2018, constitute a new type of event, with similarities to some supernovae and gamma-ray ...

'Cosmic Ring of Fire' 11 Billion Years Ago: How Did Structures in Early Universe Form?

Astronomers have captured an image of a super-rare type of galaxy -- described as a 'cosmic ring of fire' -- as it existed 11 billion years ...

ALMA Discovers Massive Rotating Disk in Early Universe

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large ...

Powerful New AI Technique Detects and Classifies Galaxies in Astronomy Image Data

Researchers have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to identify and classify all of the galaxies and stars in large data ...

New Study Examines Which Galaxies Are Best for Intelligent Life

Giant elliptical galaxies are not as likely as disk-shaped galaxies, such as our own Milky Way, to be cradles of technological civilizations, according to a recent article by a ...

Milky Way Could Be Catapulting Stars Into Its Outer Halo

Astronomers have shown that clusters of supernovas can cause the birth of scattered, eccentrically orbiting suns in outer stellar halos, upending commonly held notions of how star systems have formed ...

ESO Telescope Sees Star Dance Around Supermassive Black Hole, Proves Einstein Right

Observations have revealed for the first time that a star orbiting the supermassive black hole at the center of the Milky Way moves just as predicted by Einstein's general theory of relativity. ...

Satellite Galaxies of the Milky Way Help Test Dark Matter Theory

Physicists report tiny satellite galaxies of the Milky Way can be used to test fundamental properties of 'dark matter' -- nonluminous material thought to constitute 85% of matter in the ...
