The Hubble Space Telescope photographed a series of ghosts of quasars that existed in the past. They are seen as ethereal green objects in various forms and are the last effects of ancient quasars. These phenomena are very interesting from a scientific standpoint because they can provide information about the past of those galaxies, which were once very active.
NASA activated a new section of its website to host the application Vesta Trek, which aims to provide a detailed view of the giant asteroid Vesta. This application works in browsers allowing anyone to explore Vesta in detail thanks to its interactive maps. Among its tools, there’s also one that allows you to export topographic elements to recreate them with a 3D printer.
A combined use of the Hubble and Chandra space telescopes allowed to conduct a study of dark matter and the results were described in an article published in the journal “Science”. Currently we have no instruments to directly detect dark matter so scientists have to study it indirectly through its effects, in this case on 72 galaxy clusters to study their behavior.
A few hours ago the Soyuz TMA-16M spacecraft blasted off from the Baikonur Cosmodrome in Kazakhstan and after almost exactly six hours reached the International Space Station carrying astronaut Scott Kelly and cosmonauts Gennady Padalka and Mikhail Kornienko. The Soyuz traveled on the fast path normally used.
Generally, the members of the International Space Station crew spend about six months in space, this time there there’s a change because a very special mission lasting one year is starting. Scott Kelly and Mikhail Kornienko will spend a year on the Station to make a series of more in-depth studies on human beings reactions to life in the microgravity of space.
NASA has announced new details on the Asteroid Redirect Mission (ARM), which over the next decade aims to test new technologies for use in future manned missions in deep space. However, this mission will be accomplished by a spacecraft that will reach an asteroid, will pick up a boulder and will carry it up to the Moon to place it in a stable orbit. There, astronauts will be able to go to study it to prepare for deep space missions.
