Out near the orbit of Jupiter, a faint speck of light is moving through the black of space. At first glance it doesn’t look like much, no brighter than a thousand distant stars speckling the velvet sky behind it; indeed, it takes a big telescope make out that it is a comet.
But what a comet it could turn out … Read the rest of this article
A space rock several hundred metres across is heading towards our planet and the last-ditch attempt to avert a disaster – an untested mission to deflect it – fails. This fictional scene of films and novels could well be a reality one day. But what can space agencies do to ensure it works?

Eight years ago yesterday, ESA’s Huygens bounced, slid and wobbled its way to rest on the surface of Saturn’s moon Titan, the first time a probe had touched down on an alien world in the outer Solar System.

StarGazing Live is a program run over 3 consecutive days by the BBC at the beginning of each year. This year, it ran from Jan 8th-10th (other things have prevented me from writing out it this week).
The programs cover a range of topics in the world of astronomy and are co-presented live by Prof. Brian Cox and comedian Dara … Read the rest of this article
One of the biggest sunspots of the current solar cycle is now turning toward Earth. Named AR1654, the active region is crackling with medium-sized (M-class) flares and could be poised to break the recent spell of calm space weather around our planet. It poses a threat for even stronger eruptions. NOAA forecasters estimate a 5% chance of X-flares today.

This composite of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory’s Very Large Telescope with far-ultraviolet (1,528 angstroms) data from NASA’s GALEX and 3.6-micron infrared data acquired by NASA’s Spitzer Space Telescope. A previously unsuspected tidal dwarf galaxy candidate (circled) appears only in the ultraviolet, indicating the presence of many hot young …

ESA’s Herschel Space Observatory captured asteroid Apophis in its field of view during the approach to Earth on 5/6 January 2013. This image shows the asteroid in Herschel’s three PACS wavelengths: 70, 100 and 160 microns, respectively. Its closest pass, on 9 January 2013, brings it to 14.45 million km from Earth, 35–40 times that of the distance of the …
This artist’s concept illustrates an asteroid belt around the bright star Vega. Evidence for this warm ring of debris was found using NASA’s Spitzer Space Telescope, and the European Space Agency’s Herschel Space Observatory, in which NASA plays an important role. Image credit: NASA/JPL-Caltech
Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the … Read the rest of this article
Newly released Hubble Space Telescope images of a vast debris disk encircling the nearby star Fomalhaut, and of a mysterious planet circling it, may provide forensic evidence of a titanic planetary disruption in the system.
