GARCHING BEI MUNCHEN, Germany (ESO PR) — The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has taken the first ever image of a young, Sun-like star accompanied by two giant exoplanets. Images of systems with multiple exoplanets are extremely rare, and — until now — astronomers had never directly observed more than one planet orbiting a star similar to the Sun. The observations can help astronomers understand how planets formed and evolved around our own Sun.
The European Space Agency’s 2020 Asteroid Day virtual programme series will feature scientists, astronomers, and astronauts reaching out to audiences everywhere. Each will be in a different language and broadcast on ADTV in the week leading to Asteroid Day. Dates to be announced soon.
30 June | Asteroid Day Live From Luxembourg
Asteroid Day LIVE is back! This year we come to you with experts calling in from around the world to discuss the latest missions, discoveries, opportunities and challenges that asteroids present. This year ADLIVE will premiere on Asteroid Day (30 June) – exact times, topics, and guest line-up to be announced soon.
PARIS (ESA PR) — Asteroid 2006 QV89, a small object 20 to 50 metres in diameter, was in the news lately because of a very small, 1-in-7000 chance of impact with Earth on 9 September 2019.
In the first known case of ruling out an asteroid impact through a
‘non-detection’, ESA and the European Southern Observatory have
concluded that asteroid 2006 QV89 is not on a collision course this year – and the chance of any future impact is extremely remote.
PARIS (ESA PR) — An object from another star system that made a brief appearance in our skies guised as an asteroid turns out to be a tiny interstellar comet.
‘Oumuamua, a name that reflects the Hawaiian meaning for ‘a messenger from afar, arriving first’, was discovered by astronomers working with the Pan-STARRS survey in Hawaii in October last year as the object came close to Earth’s orbit. Follow-up observations by ESA’s Optical Ground Station telescope in Tenerife, Canary Islands, and other telescopes around the world helped determine its trajectory.
Video Caption: On Saturday, 30 June, watch live when scientists, mission planners, asteroid experts and astronauts from ESA, the European Southern Observatory and worldwide bring you the latest news and science from the work they do to help defend our planet.

Pale Red Dot campaign reveals Earth-mass world in orbit around Proxima Centauri
GARCHING BEI MUNCHEN, Germany (ESO PR) — Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than the Earth and is the closest exoplanet to us — and it may also be the closest possible abode for life outside the Solar System. A paper describing this milestone finding will be published in the journal Nature on 25 August 2016.
Today, at an international ESO/CAUP exoplanet conference in Porto, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO’s 3.6-metre telescope, reports on the incredible discovery of some 32 new exoplanets, cementing HARPS’s position as the worldâ€™s foremost exoplanet hunter. This result also increases the number of known low-mass planets by an impressive 30%. Over the past five years HARPS has spotted more than 75 of the roughly 400 or so exoplanets now known.
