This lovely abstract image of the Saturn rings is just one of the many unique photos taken by the Cassini spacecraft. The strong lines seem to cross, but they are not really – it's the spacecraft's angle and the inclination of the planet creating the illusion. Notice the thick black line that stretches horizontally? This is called Encke Gap; It is kept open by one of Saturn's smallest and most famous moons, Pan. Take a close look at Encke Gap in the middle of the picture and there you will find Pan!
The sun looks blue in this image due to an ultraviolet filter, which shows features more clearly. What stands out here is the active region in the middle of the photo. These bright arcs show strongly charged particles escaping from the sun along magnetic field lines.
The moon seems to float above the earth in this breathtaking image of the International Space Station on April 30th. On the surface of our planet you see Newfoundland, Canada, but what you really should see is the radiant blue of the atmosphere. One easily forgets how thin our atmosphere is ̵
The Hubble Space Telescope beats again with this nearly bent space-time image of a cluster of galaxies called SDSS J0150 + 2725. You'd think it's the light blue thing at the bottom, but that's not the object in question. At the top of the frame, light is diffracted, distorting the shapes of galaxies farther into the distance, and the culprit is the SDSS J0150 + 2725 galaxy clusters. While we can not see the cluster itself, we can see how it affects the surrounding space. Galaxy clusters like these are among the most massive objects in the universe, and they contain so much mass that they influence the gravity around them and distort space-time.
They are looking at a group of black holes. But we can not see black holes, you say! You're right, but what we can see is that near light is sucked into black holes. This is Sagittarius A, the supermassive black hole in the center of our Milky Way. The scientists from the Chandra X-ray Observatory have cleverly detected this black hole cluster: neutron stars emit gas, and if they are trapped in the orbit with a black hole, the black hole will deprive the star of gas and create a light trail that is within Essentially a fingerprint that marks its existence.
Welcome to space, Copernicus Sentinel-3B! This is the first image of the new satellite of the European Space Agency, which was launched to study the Earth's climate. With its all-new cameras, Sentinel-B has captured the sunset over the Antarctic. The only daylight left is in the middle, as the darkness of the night creeps up from the bottom of the frame.
Last week the sun opened again. Seen here filtered by an extreme UV light filter, which shows very high-energy radiation, the darker area is an opening in the magnetic field of the star. These coronal holes spray highly charged particles called the solar wind. This sweeps into space and eventually collides with our own magnetic field, allowing a dazzling show of the Northern Lights for those near the North and South Poles.
