Stellar bees and the most beautiful portrait of Mars. The icy surface of Europa, Saturn’s F ring and spotted the supernova in the sixteenth century in the photos.
This beautiful image of Mars was taken by the Hubble Space Telescope just 80 million kilometers away.
The aerospace company Lockheed Martin has just announced plans for a space station that would orbit around the red planet.
Formations such as this one, photographed on the Martian surface in that Arabia Terra region, would be the traces left by powerful tsunami that would devastate the red planet around 3.4 billion years ago.
According to a new study, at least two occasions gigantic meteorite would hit an ocean that covered much of the northern hemisphere: the waters had dragged toward the shore and giant boulders dug deep channels in the Martian landscape. However, the study does not convince all astronomers: it is not clear whether at the time of the hypothetical tsunami the great northern ocean of Mars there was indeed. According to the most reliable theories so far, in fact, in the period Esperian, between 3.5 and 1.8 billion years ago, the planet’s atmosphere had become thinner, much to cool the planet and prevent further accumulation large amounts of liquid water on its surface.
Sighted for the first time in 1572, the stellar explosion known as “Nova Tycho” named after the Danish astronomer (Tycho Brahe) who observed, has left gas which shine X-rays and in the radio spectrum.
The observations conducted since 2000 have allowed scientists to make a film about the expanding supernova remnant.
This image taken by Hubble shows star clusters swarming like bees around the lenticular galaxy NGC 5308, located just under 100 million light-years away in the constellation Ursa Major.
This in bold colors taken from NASA’s Galileo spacecraft shows the fine cracks running across the icy surface of Jupiter’s moon Europa, beneath which lies an ocean.
The F ring of Saturn is full of whims, jets, filaments and lumps caused by the gravitational pull of the two nearby moons, Prometheus (pictured) and Pandora.
Prometheus also occasionally enters the ring.
