Have you ever come across this kind of description of an astronomical event?
“…astronomers have witnessed a supermassive black hole blasting its galactic neighbor with a deadly beam of energy…Both galaxies are situated about 1.4 billion light-years away from Earth…The offending galaxy probably began assaulting its companion about 1 million years ago…”
How can that be, asks Sciencebase reader Adam Azman. If the event is at a …

In the late 1990s, the universe changed. The sums suddenly did not add up. Observations of the remnants of stars that exploded billions of years ago, Type Ia supernovae, showed that not only are they getting further away as the universe expands but they are moving faster and faster. It is as if some mysterious hidden force that pervades the cosmos is working against gravity and …

A cocktail of chemicals is venting in enormous jets from the oxygen-rich surroundings of a supergiant star 5000 light years from earth, according to Arizona radio astronomers. Using the the Arizona Radio Observatory’s 10m Submillimeter Telescope (SMT) on Mount Graham, which is so sensitive it could detect emissions from deep space that are weaker than a typical light bulb, the team has picked up the chemical signatures for a range …

Hot on the heels of Monday’s cosmic search engine is news from Caltech that images of the oldest known galaxies have been obtained. These heavenly bodies existed at a time when the universe was a mere 500 million years old, some 13 billion years ago.
Caltech astronomer Richard Ellis exploited “gravitational lensing”, an effect by which light from distant stars and galaxies is focused towards us by intervening massive objects. Ellis …

Want to know what time the moon will rise in your neck of the woods, which planet is in which constellation tonight, or when the Internation Space Station will next be overhead? There is not much stargazing going in England at the moment, too much H20 falling from the sky, but eZipSky’s free service for amateur astronomers in the US, is a kind of search engine for heavenly bodies.
The eZipSky …

A plateau on the planet Mars called Home Plate looks like it had a volcanic past, according to the latest data from NASA’s rover Spirit. The data also support earlier hints at that water once existed at or beneath the planet’s surface.
Home Plate has a finely layered appearance and so made it a tantalizing target for Spirit, according mission controller Steve Squyres. The rover captured its first panoramic image …

Sending astronauts up to our nearest star to reignite the Sun, the premise of sci-fi movie Sunshine, is truly the least of our problems when we are currently faced with global climate change, global terrorism, and global economic collapse. Nevertheless, astronomers are concerned about recent findings regarding the hot gas surrounding our star and its stellar neighbours. Put simply they cannot find them.
A team led by Martin Barstow of Leicester …
