This one here were alien spacecraft. the report also does not rule out the possibility. and joining us now is a professor of astrophysics at the university of rochester, adam frank. he s author of the book life of the stars, alien worlds, and the fat fat of the architect fate of the earth, typo, pardon me, which we re more interested in. at this point it doesn t rule out they re alien. it doesn t rule it out, but they re saying there s a chance. well, you know, there s a very long distance between not ruling out and claiming it s alien. one of the things i work on is looking for life in the universe on distant planets, and we have a very, very high bar of evidence if we re going to make that claim. if i tried to make that claim, my colleagues would beat me up pretty bad as they should. the thing about ufos is they re ....

The surface of the sun churns with energy and frequently ejects masses of highly-magnetized plasma towards Earth. Sometimes these ejections are strong enough to crash through the magnetosphere the natural magnetic shield that protects the Earth damaging satellites or electrical grids. Such space weather events can be catastrophic.
Astronomers have studied the sun s activity for centuries with greater and greater understanding. Today, computers are central to the quest to understand the sun s behavior and its role in space weather events. ....

Gaps in the knowledge. last year, the defence department released a series of classified videos appearing to show an unidentified flying object off the coast of california in 2015. my gosh! we re going against the wind. but if you were hoping the report will have a series of neat, easily digestible explanations, you ll be disappointed. former national intelligence directorjohn ratcliffe has already said that the paper would include information that cannot easily be explained, which no doubt ratchets up the intrigue. dr adam frank is a professor of astrophysics at the university of rochester. he and his colleagues were recently awarded a nasa grant to study signs of intelligent life elsewhere in the universe. hejoins us now. ....

UMass Amherst astronomer reveals never-before-seen detail of the center of our galaxy

AMHERST, Mass. - New research by University of Massachusetts Amherst astronomer Daniel Wang reveals, with unprecedented clarity, details of violent phenomena in the center of our galaxy. The images, published recently in
Monthly Notices of the Royal Astronomical Society, document an X-ray thread, G0.17-0.41, which hints at a previously unknown interstellar mechanism that may govern the energy flow and potentially the evolution of the Milky Way.
The galaxy is like an ecosystem, says Wang, a professor in UMass Amherst s astronomy department, whose findings are a result of more than two decades of research. We know the centers of galaxies are where the action is and play an enormous role in their evolution. And yet, whatever has happened in the center of our own galaxy is hard to study, despite its relative proximity to Earth, because, as Wang explains, it is obscured by a dense fog of gas and dust. Re ....
