The ALMA and APEX telescopes have peered deep into space — back to the time when the Universe was one tenth of its current age…
Astronomers using ESA’s XMM-Newton space observatory have probed the gas-filled haloes around galaxies in a quest to find ‘missing’ matter thought to reside there, but…
The first stars in the universe blazed to life about 200 to 400 million years after the big bang. Observing those very first individual stars…
Analysis of gravitational lensing data by an international research team reveals that the evolution of galaxy clusters is dictated by a surprisingly simple law, which…
Young scientists from ITMO University have explained how neutron stars generate intense directed radio emission. They developed a model based on the transitions of particles…
Astronomers are beginning to understand what happens when black holes get the urge to roam the Milky Way. Typically, a supermassive black hole (SMBH) exists…
Saturn’s rings display their subtle colors in this view captured on August 22, 2009, by NASA’s Cassini spacecraft. The particles that make up the rings…
Hydrogen sulfide, the gas that gives rotten eggs their distinctive odor, permeates the upper atmosphere of the planet Uranus – as has been long debated,…
A ‘deep learning’ algorithm trained on images from cosmological simulations has been surprisingly successful at classifying real galaxies in Hubble images. A machine learning method…
This image of Jupiter’s iconic Great Red Spot and surrounding turbulent zones was captured by NASA’s Juno spacecraft. The color-enhanced image is a combination of…
NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission has released its fourth year of survey data. Since the mission was restarted in December 2013,…
This pretty, cloud-like object may not look much like a galaxy — it lacks the well-defined arms of a spiral galaxy, or the reddish bulge…
Researchers have developed a new way to improve our knowledge of the Big Bang by measuring radiation from its afterglow, called the cosmic microwave background…
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant…
As Curiosity rover marches across Mars, the red planet’s watery past comes into clearer focus. In early 2017 scientists announced the discovery of possible desiccation…
Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of…
Number 1: Westerlund 2 — Hubble’s 25th Anniversary Image This NASA/ESA Hubble Space Telescope image of the cluster Westerlund 2 and its surroundings has been…
