Fifty-five million light-years away from Earth is a galaxy called M87. This galaxy is home to an ultramassive black hole recently photographed by the Event Horizon telescope. In this image, which combines visible and infrared light, we can see M87 in the center and an enlarged section of gas jets ejected near the black hole. Because the black holes are so massive, if something passes near one of them, like a star for example, the mass rips the object that sends the gas and dust at speeds high enough for them to start shining electromagnetic radiation. It's this destruction tag that even allows us to locate black holes.
And, just 8000 light-years from Earth in our own galaxy, the Milky Way, is a black hole that is part of a binary star system called V404 Cygni. This black hole devours its stellar companion, which releases jets of material into space. But it's not your average black hole. Scientists found that these jets were moving very fast, like a spinning top starting from the center of the black hole. This material rotates so fast, in fact, that the black hole is actually lagging the space-time around it.
We are used to examining impact craters throughout the solar system. The Moon and Mars are covered, but we rarely have the chance to see them on Earth. This photo was taken from the International Space Station over the impact crater of Manicouagan, Quebec, Canada. If you look just to the right of the river, you'll see a circle bordered with white, it's the impact crater, created about 200 million years ago by an asteroid three miles wide. But what would happen if another asteroid would shoot in the sky and hit the Earth! NASA is still working on "planetary defense" measures and is monitoring asteroids and comets within 30 million kilometers of the planet.
The outer planets have long been neglected by our spaceship: only one mission studied Neptune and Uranus, it was Voyager 2 almost 30 years ago. He took this picture of Neptune, the deepest blue marble, and it's one of the only ones we have from this eighth planet farthest from the land. NASA is now beginning to think about what should be done to return to Uranus and Neptune. And a lot of things have changed. From the observations of the Earth, we know that the dark oval storm has disappeared and that others have taken its place. Neptune and Uranus are absolute mysteries: it's time to return!
The NASA InSight lander may be immobile, but that does not mean it can not capture interesting scenes on Mars. In this image taken on April 25, InSight took a picture of a cloudy Martian sunset. Imagine yourself sitting on the deck of the LG with your darling, an oxygen tank and ice – cream astronaut.
Once the clouds cleared, InSight continued to take pictures (including his articulated arm). The sun seems small and distant as it dives below the horizon.
