Space Week photos: watch, ma, no!


NASA's Curiosity rover is an expert who takes self-assessments on Mars, and this latest photo was caught on January 15 at Rock Hall drilling. It is actually 57 separate images that are sewn to show another working day on the red planet. After six years of work and driving, the rover is looking rather dusty and dirty, but it still removes and carries out science (too tweeting and 'graming!' from 100 million miles away.

New Year's Day NASA's New Horizons visited the most distant object ever made by the spacecraft – the tiny, ice rock called MU69 2014. From a distance, it looked like a ridiculously elongated light point, but thanks to the flight, we now know that MU69 is actually a deep snowman. This newly created high-resolution image shows MU69 as two distinct spheres called contact binary. Although this original object might look like bowling pants, MU69 is really complete information on the first days of our solar system.

In space photographs, we often see the death of the stars, but rarely do we see the destruction of the galaxy. This region is called the Comoma galaxy cluster, and the right-hand spiral D100 is not appropriate for the cluster severity. Its material is pulled slowly and shot into space. After removing the largest galaxy material from the D100, it will lose its ability to create new stars and remain a relic containing only the ancient red stars.

Scientists have long wondered why in the first days of the universe there were so huge black holes so common. A new study funded by NASA and the National Science Foundation used the distribution of dark substances in the new galaxies to better understand what might be feeding these dense objects so early. Sometimes when the stars die, they turn into a supernova and explode all over the place. Alternatively, if they are very dense, they can quickly use fuel and turn into a black hole. This image, made from the simulation of supercomputers by the Georgian Institute of Technology, shows the halo of dark matter around three supermassive stars, which can eventually turn into a supermassive black hole.

Our galaxy's astronomical tapestry shines too early in the very large telescope of the European Southern Observatory, located in the Atacama desert in Chile. (Its 300 clear nights a year cannot be beaten to see space.) Here is a unit telescope 4 (Yepun) that receives two lasers that will serve as a guideline during the observation. Astronomers use these false stars to calibrate their telescopes and compare another star's brightness.

There is an unknown force in space that is likely to be the key to the rapid acceleration and expansion of the universe. Astronomers call it dark energy. This illustration shows how scientists think dark energy in galaxies may have changed over time. Thanks to NASA's Chandra X-ray Observatory and the spacecraft of the European Space Agency XMM-Newton, we are approaching to understand how this power may have changed between a billion years of astral bodies.
