New images taken with the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile have revealed otherwise invisible details of our Sun, including a new view of the dark, contorted centre of a sunspot that is nearly twice the diameter of the Earth. The images are the first ever made of the Sun with a facility where ESO is a partner. The results are an important expansion of the range of observations that can be used to probe the physics of our nearest star. The ALMA antennas had been careful...

ESA astronaut Thomas Pesquet completed his first spacewalk last Friday together with NASA astronaut Shane Kimbrough. The duo spent five hours and 58 minutes outside the International Space Station to complete a battery upgrade to the outpost's power system. The main task was to replace nickel-hydrogen batteries that store electricity from the Station's solar panels with newer lithium-ion batteries that arrived recently aboard Japan's cargo vessel. Thomas and Shane's speed allowed them to p...

Searching for planets around other stars is a tricky business. They’re so small and faint that it’s hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a unique way: by a shadow that is sweeping across the face of a vast pancake-shaped gas-and-dust disk surrounding a young star. The planet itself is not casting the shadow. But it is doing some heavy lifting by gravitationally pulling on material near the star and warping the inner...

This week, ESA deep-space radio dishes on two continents are listening for signals from the international Cassini spacecraft, now on its final tour of Saturn. ESA's sensitive tracking antennas at New Norcia, Western Australia, and Malargue, Argentina, are being called in to help with crucial observations during Cassini's last months in orbit, dubbed the 'Grand Finale'. The Cassini-Huygens mission is one of the most successful exploration endeavours ever. Launched in October 1997, the Ca...

Monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes. But they give themselves away when material they feed on emits high-energy X-rays that NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) mission can detect. That's how NuSTAR recently identified two gas-enshrouded supermassive black holes, located at the centers of nearby galaxies. "These black holes are relatively close to the Milky Way, but they have remained hidden from us un...

Some of us may be easing ourselves gently into the New Year, but for the team readying Sentinel-2B for liftoff on 7 March it's full steam ahead. On 5 January, the satellite was shipped from ESA's site in the Netherlands - where it had been undergoing testing since June - and arrived safe and sound in French Guiana the following day. The Sentinel-2 mission is designed as two satellites working in tandem - Sentinel-2A has been in orbit since June 2015. Offering 'colour vision' for Europe'...

Sentinel-2B has touched down in French Guiana, bringing the second satellite for Europe’s Copernicus program closer to its early March orbiting by Arianespace on a Vega lightweight launch vehicle. Arriving at Félix Eboué Airport near Cayenne last week, Sentinel-2B was delivered by a chartered Antonov An-124 cargo jetliner. Following its unloading process, the satellite was readied for transfer by road to the Spaceport. As a follow-on to Sentinel-2A – lofted by a...

Careful sleuthing through decade-old images has enabled ESA's asteroid team to decide that a newly discovered space rock poses little threat of hitting Earth any time soon. Spotting a previously unknown asteroid for the first time always raises the big question: is there a risk it will impact Earth? Yet, upon discovery, analysts often have very little to go on. The initial image from the observatory, survey team or individual backyard astronomer who spotted the rock typically gives only ba...

ESO has signed an agreement with the Breakthrough Initiatives to adapt the Very Large Telescope instrumentation in Chile to conduct a search for planets in the nearby star system Alpha Centauri. Such planets could be the targets for an eventual launch of miniature space probes by the Breakthrough Starshot initiative. ESO, represented by the Director General, Tim de Zeeuw, has signed an agreement with the Breakthrough Initiatives, represented by Pete Worden, Chairman of the Breakthrough Prize ...

Interstellar forecast for a nearby star: Raining comets! NASA’s Hubble Space Telescope has discovered comets plunging onto the star HD 172555, which is a youthful 23 million years old and resides 95 light-years from Earth. The exocomets — comets outside our solar system — were not directly seen around the star, but their presence was inferred by detecting gas that is likely the vaporized remnants of their icy nuclei. HD 172555 represents the third extrasolar system wher...
