Hubble Asteroid Hunter, A Citizen Science Project Finds 1,701 Asteroid Trails In Archival Images

Image
In its 32 years of observations , the NASA/ ESA Hubble Space Telescope has built up an archive containing hundreds of thousands of targeted observations of galaxies, the cluster of galaxies, gravitational lenses and nebulae. At times, closer objects such as asteroids pass the telescope's field of view while other targets are being observed, leaving the images' trails. Image Credits: Pixabay On International Asteroid Day in 2019, astronomers launched the Hubble Asteroid Hunter , a citizen science project on the Zooniverse platform (the world’s largest citizen science platform), aiming to visually identify asteroids in archival images from the European Space Agency Hubble Space Telescope (eHST) archive and examine their properties. The initiative was developed by the European Science and Technology Centre (ESTEC) and the European Space Astronomy Centre's Science Data Centre (ESDC), collaborating with Google and Zooniverse. Firstly, the astronomers detected more than 37,000

Rosetta Update: Landing site options not very safe [Coffee-byte]

Image
In an interesting turn of events, scientists at the European Space Agency are having a difficult time determining the perfect landing spot for Rosetta 's probe, Philae . An earlier update from the agency at the beginning of the month had revealed that 5 landing spots had been shortlisted from the the probable list of 10 chosen first.  Comet 67P. Image source: www.dailymail.co.uk But further analysis of these sites has shown that none of them seem safe enough for Philae to land. Rosetta has been returning high resolution images of these probable sites of landing and the comet 67P seems to have layered cliffs along most of the landing sites that have been identified so far. Philae needs a landing strip close to 1 km long and hitting one of the layered cliffs might end its mission prematurely.  The comet's duck shaped body does not make life easier as well. There is sufficient landing space on some other sites on the comet but due to their location, they do not h

5 reasons that make Rosetta a SUPERSTAR!

Artist's rendition of Rosetta approaching comet 67P Image Source: ESA For the next few days (and probably many many years), you are likely to come across people speak of the greatness of 'Rosetta' and about her achievements and before you start thinking that the Rosetta is some entrepreneur, social worker, sportswoman or the worst, a movie star, let us make it very clear that Rosetta is actually a spacecraft. and still a Superstar! Here are 5 things that have make Rosetta famous! Rosetta, is a spacecraft built by the European Space Agency , at a cost of 1.3 billion Euros, with the aim to study the comet 67P/ Churyumov- Gerasimenko. Discovered in 1969, the comet orbits around our Sun every 6.6 years and Rosetta's mission to understand what this comet is made up. The mission will give us scientists further information on how our Solar System originated and evolved, since our Sun, planets and all the comets are made up of the same pre-solar nebula that existed ov
