The Chinese space lab, Tiangong-1, was in the news for all the wrong reasons. The media frenzy over the school bus-sized space station suggested that bits of its debris could very well fall anywhere between 43 degrees north and 43 degrees south latitudes, practically all of Earth’s most populated area. The “uncontrolled” fall of a ...
Astronomers are back in the dark about what dark matter might be, after new observations showed the mysterious substance may not be interacting with forces other than gravity after all. Dr. Andrew Robertson of Durham University presented the new results to the European Week of Astronomy and Space Science in Liverpool. Three years ago, a ...
It might sound like something from a science fiction plot — astronauts traveling into deep space being bombarded by cosmic rays — but space radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars, new research from the University of New Hampshire’s Space Science Center cautions ...
Astronomers have discovered that all galaxies rotate once every billion years, no matter how big they are. The Earth spinning around on its axis once gives us the length of a day, and a complete orbit of the Earth around the Sun gives us a year. “It’s not Swiss watch precision,” said Professor Gerhardt Meurer ...
Lawrence Livermore National Laboratory (LLNL) scientists are part of a national planetary defense team that designed a conceptual spacecraft to deflect asteroids that are Earth-bound, and evaluated whether it would be able to nudge a massive asteroid — which has a remote chance of hitting Earth in 2135 — off course. The design and case ...
Trailing Earth’s orbit at 94 million miles away, the Kepler space telescope has survived many potential knock-outs during its nine years in flight, from mechanical failures to being blasted by cosmic rays. At this rate, the hardy spacecraft may reach its finish line in a manner we will consider a wonderful success. With nary a ...
Notanee Bourassa knew that the purple lights he was seeing in the night sky were not normal. Bourassa, an I.T. technician in Regina, Canada, trekked outside of his home on July 25, 2016, around midnight with his two younger children to show them a beautiful moving light display in the sky — an aurora borealis. ...
Much like detectives study fingerprints to identify the culprit, scientists used NASA’s Hubble and Spitzer space telescopes to find the “fingerprints” of water in the atmosphere of a hot, bloated, Saturn-mass exoplanet some 700 light-years away. And they found a lot of water. In fact, the planet, known as WASP-39b, has three times as much ...
In the real world, your past uniquely determines your future. If a physicist knows how the universe starts, he or she can calculate its future for all time and all space. But a UC Berkeley mathematician has found some types of black holes in which this law breaks down. If someone were to venture into ...
The day when astronauts go on deep-space missions, human waste may end up being a valuable food resource — that’s right, transform human waste into food. A team of researchers has shown that it is possible to rapidly break down solid and liquid waste to grow food. The idea is not new. Astronauts aboard the ...
