Ram pressure is the pressure exerted on a body when it passes through a fluid medium; this causes a drag force that is exerted on the body. The same pressure appears when a galaxy is moving through an intergalactic gas, and in this case, the ram pressure can sweep a significant part of the intergalactic [...]

Hubble has had a lot of problems in recent days, but now the telescope we love the most is up an running, and in a great shape too. “This marks a new beginning for Hubble,” said Ed Weiler, associate administrator for NASA’s Science Mission Directorate at NASA Headquarters. “The telescope was given an extreme makeover and [...]

Planet Mars will be the brightest we’ll (probably) ever have a chance to see it, and it will be as large as the moon, even for the naked eye ! I can’t even imagine what it will be like, but I bet the Red Planet will be absolutely spectacular, and it’s something you definitely don’t [...]

This is a wicked one for sure! Basically, nobody really knows what’s going on there, except for the fact that it probably involves a supermassive black hole. The whole picture seems to be rather a Dali painting of an eye, as the red-in-infrared spiral wraps around the smaller blue companion galaxy. The pink lighting you [...]

Astronomy & Astrophysics has published spectroscopic observations of one of the hottest stars discovered so far - a white dwarf called KPD 0005+5106. The observations were made using the space-based Far-Ultraviolet Spectroscopic Explorer (FUSE), showing that the temperature can reach 200 000 K at the surface of the star. Temperatures can get so high that [...]

Beta Pictoris (β Pic / β Pictoris) is part of a group of hot young stars that have the same age and motion through stage. It’s best known for the fact that it’s surrounded by a dusty ‘debris’ disc. This disc is a result of collisions between planetary ‘embryos’ and asteroids, or other such objects. Recently, [...]

After more than 400 years, science-enthusiasts and not only can finally pay a tribute to the man who revolutionized people’s perception of the Universe. After having analyzed DNA taken from two strands of hair and a tooth, scientists finally concluded that the remains found in Frombrok Cathedral in Poland are, in fact, the ones of [...]

Despite the fact that they have worked round the clock for fixing Hubble, it seems NASA engineers have once again hit a snag and they’re currently trying to figure out what is the next step. The telescope stopped sending pictures three weeks ago, and at first it was believed that it wouldn’t take that long [...]

Using the RHESSI spacecraft, scientists managed to calculate the Sun’s roundness with a level of precision that surpasses anything of this type that has been attempted before. They found that the star which the Eart rotates around is not quite a sphere, but it has a thin “cantaloupe skin”. This skin causes the equatorial radius to [...]

Recently, a team of researches (with the help of the National Science Foundation’s (NSF) Very Long Baseline Array (VLBA) and a host of international telescope partners) have managed to get the clearest observation yet of the “core” of a black hole.A black hole is a region of space in which the gravitational field is so [...]
