Supernovae are one of the most energetic and brightest events in the cosmos, often so powerful they outshine whole galaxies. They’re considered to play a major role in our understanding of the Universe, which is why scientists have invested so much time and effort into studying them. A recent study of X-ray and ultraviolet observations from […]
Strange, huge explosions apparently fueled by solar energy are detonating just above the surface of Venus, a surprising new study concludes. Explosive Venus This is not the first time this unusual phenomenon, called ‘hot flow anomaly’ (of HFA) was observed; such events have been previously spotted above Earth, and possibly Saturn and Mars – but […]
It’s been less than a month since we published the last thing about the Cassini probe, and the amazing spacecraft has done it again; this time it detected a thin, oxygen atmosphere, on a moon of Saturn – Dione. The study was published in the Geophysical Research Letters At 1122 km in diameter, Dione is […]
Most of us tend to believe the Earth is a safe heaven, with little regard to outerwordly consequences. The truth is our planet, although without a doubt a true gem within our galaxy, is susceptible to a slew of events triggered from within or well beyond our solar system. A lot of them are very […]
Europe aims for the stars: known as the Solar Orbiter will fly towards the Sun and get closer to it than any other man made object has; also, ESA will launch two other missions with the purpose of studying dark matter and dark energy. Closer to the Sun The mission was adopted today, and it […]
Astronomers at UC Santa Cruz have set a new benchmark for cosmological research for decades to come maybe, after successfully simulating the forming of distant galaxies, like our very own Milky Way, under the mysterious forces of dark matter and dark energy. Named Bolshoi – for the Russian word meaning “grand” or “great” – the simulation’s […]
Every three hours throughout the day, magnetic observers located all around our planet measure the biggest magnetic change that their instruments can record during that period. All the measured values are averaged all over the world and an index is obtained (the Kp index), telling researchers how disturbed the Earth’s magnetic field is on a […]
If you look at this picture, you will probably see what can only be described as an unremarkable, even faint star. But this ancient star, in the constellation of Leo (The Lion), called SDSS J102915+172927 has astrophysicists scratching their heads, searching for new answers. A team of European astronomers using ESO’s Very Large Telescope (VLT) […]
For the past 14 years, astronomers have been scratching their heads trying to find out just where does the water in Saturn’s upper atmosphere comes from; now, ESA’s Herschel space observatory has solved that mystery – the water is expelled from Enceladus, one of the planet’s moons. Enceladus is eliminating about 250 kilograms of water […]
