Possible Marker of Life Spotted on Venus

Possible Marker of Life Spotted on Venus An international team of astronomers today announced the discovery of a rare molecule — phosphine — in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could […]

ALMA sees most distant Milky Way look-alike

ALMA sees most distant Milky Way look-alike Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The galaxy is so far away its light has taken more than 12 […]

Stunning Space Butterfly Captured by ESO Telescope

Stunning Space Butterfly Captured by ESO Telescope Resembling a butterfly with its symmetrical structure, beautiful colours, and intricate patterns, this striking bubble of gas — known as NGC 2899 — appears to float and flutter across the sky in this new picture from ESO’s Very Large Telescope (VLT). This object has never before been imaged […]

A Cosmic Mystery: ESO Telescope Captures the Disappearance of a Massive Star

A Cosmic Mystery: ESO Telescope Captures the Disappearance of a Massive Star Using the European Southern Observatory’s Very Large Telescope (VLT), astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright and partially obscured by dust. An alternative explanation is […]

Hot stars are plagued by giant magnetic spots, ESO data shows

Hot stars are plagued by giant magnetic spots, ESO data shows Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. Not only are these stars plagued by magnetic spots, some also experience superflare events, explosions of energy several million times more energetic […]

ESO Telescope Sees Signs of Planet Birth

ESO Telescope Sees Signs of Planet Birth Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the telltale signs of a star system being born. Around the young star AB Aurigae lies a dense disc of dust and gas in which astronomers have spotted a prominent spiral structure with a […]

ESO Instrument Finds Closest Black Hole to Earth

ESO Instrument Finds Closest Black Hole to Earth A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered a black hole lying just 1000 light-years from Earth. The black hole is closer to our Solar System than any other found to date and forms part of a triple system that […]

ESO Telescope Observes Exoplanet Where It Rains Iron

ESO Telescope Observes Exoplanet Where It Rains Iron Researchers using ESO’s Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night […]

New ESO Study Evaluates Impact of Satellite Constellations on Astronomical Observations

New ESO Study Evaluates Impact of Satellite Constellations on Astronomical Observations Astronomers have recently raised concerns about the impact of satellite mega-constellations on scientific research. To better understand the effect these constellations could have on astronomical observations, ESO commissioned a scientific study of their impact, focusing on observations with ESO telescopes in the visible and […]

ESO Telescope Sees Surface of Dim Betelgeuse

ESO Telescope Sees Surface of Dim Betelgeuse Using ESO’s Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star’s surface show not only the fading red supergiant but also how its apparent shape is changing. ESO News […]

ALMA catches beautiful outcome of stellar fight

ALMA catches beautiful outcome of stellar fight Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, have spotted a peculiar gas cloud that resulted from a confrontation between two stars. One star grew so large it engulfed the other which, in turn, spiralled towards its partner provoking it into shedding […]

ESO Observations Reveal Black Holes’ Breakfast at the Cosmic Dawn

ESO Observations Reveal Black Holes’ Breakfast at the Cosmic Dawn Astronomers using ESO’s Very Large Telescope have observed reservoirs of cool gas around some of the earliest galaxies in the Universe. These gas halos are the perfect food for supermassive black holes at the centre of these galaxies, which are now seen as they were […]
