• November 2015

Каждую минуту более 180 кг водорода и 3 кг гелия улетучиваются из атмосферы Земли в открытый космос. Астрофизик Аньяли Трипатхи изучает феномен планетарного ветра, и в этом очаровательном и доступном для понимания выступлении она рассматривает, как данный процесс может однажды (через миллиарды лет) превратить нашу голубую планету в красную.

The Martian

Near and dear to my heart because of the time I’ve spent at JPL working on the Mars Rovers, this is a fun read. Even though it’s a work of fiction, it conveys the exhilaration of working on space missions at NASA.

Bill Bryson | Broadway Books, 2004 | Book

A Short History of Nearly Everything

If you want more background about astronomy or any other science topic, this is a witty, easy-going work that puts it all together. Great perspectives on how unlikely it is that we’re here and how much had to go right to get here – both from the side of nature and scientific discovery.

Brian Cox | Watch

Wonders of the Solar System and Wonders of the Universe

Wonderful programs tying together disparate astronomical objects to make clear points about the forces and features that govern the Universe. Brian Cox is a delightful guide, who chooses the best examples to highlight insightful points. I never give an outreach talk without first re-watching parts of this show for inspiration.
