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'...

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...

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...

NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system - a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively. "Lucy will visit a target-rich environment of Jupiter's mysterious Trojan asteroids, while Psyche will study a unique metal...

This spectacular new image is one of the largest near-infrared high-resolution mosaics of the Orion A molecular cloud, the nearest known massive star factory, lying about 1350 light-years from Earth. It was taken using the VISTA infrared survey telescope at ESO's Paranal Observatory in northern Chile and reveals many young stars and other objects normally buried deep inside the dusty clouds. The new image from the VISION survey (VIenna Survey In Orion) is a montage of images taken in the near...

NASA has selected a science mission that will allow astronomers to explore, for the first time, the hidden details of some of the most extreme and exotic astronomical objects, such as stellar and supermassive black holes, neutron stars and pulsars. Objects such as black holes can heat surrounding gases to more than a million degrees. The high-energy X-ray radiation from this gas can be polarized - vibrating in a particular direction. The Imaging X-ray Polarimetry Explorer (IXPE) mission will ...
