NEO Coordination Centre's observing campaign to track the fly-by of BepiColombo
ESA's NELIOTA project detects the flash of light produced when an asteroid collides energetically with the lunar surface and recently recorded its 100th impact.
Planetary Defence office we took the opportunity of the Solar Orbiter launch to perform an observational exercise, attempting to image the departing spacecraft with a ground based optical telescope.
The year has just started, and we already have a very interesting discovery of a new and so far unique asteroid.
If you check our current risk list, you will notice that a significant number of objects in the top positions are extremely “old”, discovered in the first decade of the century.
Over the past week, the Near-Earth Object (NEO) community in general, and ESA’s NEO Coordination Centre (NEOCC) in particular, have been involved in an interesting example of the process of discovering a new and exceptional object.
One month ago, NEOCC team ruled out the possibility that asteroid 2006 QV89 would impact the Earth this September by making a “non-detection”, i.e. observing the area of the sky where the asteroid would appear if it were on a collision course with our planet - and not detecting it.
On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon.
A new paper by Alessio Del Vigna and collaborators, published this week in the Astronomy and Astrophysics journal, significantly revised the chances of impact of (410777) 2009 FD.
Asteroid 2006 QV89, a small object 20 to 50 meters in diameter, has been in the news lately, because of a very small 1-in-7000 chance of impact with the Earth on 9 September 2019.
Hera will show us things we have never seen before. Astrophysicist and Queen guitarist Brian May tells in the next video the story of the ESA mission that would be humanity's first-ever spacecraft to visit a double asteroid
For the fifth year, Asteroid Day is going to be celebrated worldwide on 30 June.
ESA’s Planetary Defence Office (PDO) has participated with several presentations at the 6th IAA Planetary Defense Conference held in College Park, near Washington, between 29 April and 3 May.
A newly-established collaboration between our team and the Instituto de Astrofísica de Canarias (IAC) led to the first-ever observation of an NEA with the 10.4 m Gran Telescopio Canarias (GTC). We targeted 2019 DS1, a high-rated NEO in our risk list, when it was already as faint as magnitude 25.7.
The number of known near-Earth asteroids (NEAs) reached the round total of 20 000 this week. This family of asteroids whose orbit brings them close to Earth is steadily growing at a pace of roughly 160 new discoveries each month, thanks to the work done by the main asteroid surveys.
A few months ago a long thin tail was noticed on main belt asteroid (6478) Gault. An international collaboration led by scientists of the Institute for Astronomy of the University of Hawaii published a paper today explaining the mechanism that led to this sudden onset of activity.
Every few hours observing the Moon, ESA’s ‘NELIOTA’ project discovers a brilliant flash of light across its surface – the result of an object hurtling through space and striking our unprotected rocky neighbour at vast speed. Based at the Kryoneri telescope of the National Observatory of Athens, this important project is now being extended to January 2021.
Andrea Milani, professor of mathematics at Pisa University, passed away unexpectedly last Wednesday while cycling near Pisa. With his deep knowledge and understanding on the Solar System dynamics, Andrea was a pioneer in a discipline started by him and a few others at the end of the past century: asteroid impact monitoring.
Registration is open for the ESA NEO and Debris Detection Conference - Exploiting Synergies, which will be held at ESA/ESOC, Darmstadt, Germany, 22 - 24 January 2019. The deadline for the submission of abstracts is 1 October 2018.
