Galactic fireworks: new ESO images reveal stunning features of nearby galaxies

Galactic fireworks: new ESO images reveal stunning features of nearby galaxies A team of astronomers has released new observations of nearby galaxies that resemble colourful cosmic fireworks. The images, obtained with the European Southern Observatory’s Very Large Telescope (ESO’s VLT), show different components of the galaxies in distinct colours, allowing astronomers to pinpoint the locations […]

Mystery of Betelgeuse’s dip in brightness solved

Mystery of Betelgeuse’s dip in brightness solved When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new images of the star’s surface, taken using the European Southern Observatory’s Very Large Telescope (ESO’s […]

New telescope at ESO’s La Silla joins effort to protect Earth from risky asteroids

New telescope at ESO’s La Silla joins effort to protect Earth from risky asteroids Part of the world-wide effort to scan and identify near-Earth objects, the European Space Agency’s Test-Bed Telescope 2 (TBT2), a technology demonstrator hosted at ESO’s La Silla Observatory in Chile, has now started operating. Working alongside its northern-hemisphere partner telescope, TBT2 […]

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 […]
