Talk about getting a piece of rock: NASA OSIRIS-REx arrived at the nearby land-asteroid Benna earlier this week. Benna, which is orbiting the Sun, can be seen here covered with dirt, smaller rocks and occasional boulders. After two years and on the 1.2 billion-kilometer journey, OSIRIS-REx was just 11 miles away from the surface when it made this photo that almost filled the frame. Eventually, the spacecraft will collect a sample of the asteroid to bring it back to the early solar system research. So far, it has to map the surface for about a year before they choose, a little less rock space that could be bathed.
The space ship Juno saw a dolphin-shaped cloud on the southern mild Jupiter belt a few weeks ago. The atmosphere directly beneath it also has the appearance of wave fluctuations, which makes this relatively oceanic scene for the giant gaseous planet. Jupiter's clouds and thunderstorms are always something they see, but this swim dolphin looks like it was drawn on mulberry trees.
This image contains the quantity – more than 1000 galaxies to be specific. The Hubble Space Telescope recently studied a group of spherical clusters that are collectively gathered in the so-called Coma galaxy cluster. Galaxies in clusters are smaller than conventional galaxies, but that does not mean they are trivial: These objects are better indicators of gravitational strains in the cluster, and such anomalies point to the existence of invisible matter-dark matter – which is not exactly well understood. And even though it's about 300 million light-years from the Earth and a blast from the past, this Coma star cluster is finally being researched by Hubble's scientists.
Have you ever wondered how the violent event of exploding stars looks? Well, here you go. Hubble captured this photograph of the rest of the supernova called SNR 0454-67.2. These gas struts were probably a supernova type 1a explosion that occurs when a dead white dwarf star starts stealing material from a nearby star – eventually collecting as much mass as it explodes. There is a swirl of gas and dust.
Astronauts at the International Space Station are demanding Earth observers with seats in the first place: they are in orbit 250 kilometers up and can see 16 exits and sunsets a day. On this sloping photograph of Alexandra Gersta of the European Space Agency, you can see the lights of civilization on the ground along with a clear reminder of how incredibly promising the atmosphere that keeps life is really only a few dozen miles above the surface.
Sun Entertainment: This image is compiled from data from the Proba2 space probe, a spacecraft around the Earth that collects pole appearance data. Now this image is not exactly symmetrical; that's because the sun's crown is constantly changing and transforming. The Dark Center also reveals a coronal hole over a pole – a great source of solar wind. It's like looking at Sauron's eye, but at least without the danger of orcs.
