First interstellar comet may be the most pristine ever found

First interstellar comet may be the most pristine ever found New observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) indicate that the rogue comet 2I/Borisov, which is only the second and most recently detected interstellar visitor to our Solar System, is one of the most pristine ever observed. Astronomers suspect that the […]

Powerful stratospheric winds measured on Jupiter for the first time

Powerful stratospheric winds measured on Jupiter for the first time Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, a team of astronomers have directly measured winds in Jupiter’s middle atmosphere for the first time. By analysing the aftermath of a comet collision from the 1990s, the […]

Most distant quasar with powerful radio jets discovered

Most distant quasar with powerful radio jets discovered With the help of the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered and studied in detail the most distant source of radio emission known to date. The source is a “radio-loud” quasar — a bright object with powerful jets emitting at radio wavelengths […]

Puzzling six-exoplanet system with rhythmic movement challenges theories of how planets form

Puzzling six-exoplanet system with rhythmic movement challenges theories of how planets form Using a combination of telescopes, including the Very Large Telescope of the European Southern Observatory (ESO’s VLT), astronomers have revealed a system consisting of six exoplanets, five of which are locked in a rare rhythm around their central star. The researchers believe the […]

Stars and Skulls: new ESO image reveals eerie nebula

Stars and Skulls: new ESO image reveals eerie nebula This ethereal remnant of a long dead star, nestled in the belly of The Whale, bears an uneasy resemblance to a skull floating through space. Captured in astounding detail by ESO’s Very Large Telescope (VLT), the eerie Skull Nebula is showcased in this new image in […]

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 […]
