NASA Discusses Discovery of Earth-Size, Habitable-Zone Planets

Original air date: Feb. 22, 2017 10 a.m. PT (1 p.m. ET, 1800 UTC) NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water. The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water — key to life as we know it — under the right atmospheric conditions, but the chances are highest with the three in the habitable zone. The briefing participants were: Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA Headquarters in Washington Michael Gillon, astronomer at the University of Liege in Belgium Sean Carey, manager of NASA’s Spitzer Science Center at Caltech/IPAC, Pasadena, California Nikole Lewis, astronomer at the Space Telescope Science Institute in Baltimore Sara Seager, professor of planetary science and physics at Massachusetts Institute of Technology, Cambridge For more information on exoplanets, visit: http://exoplanets.nasa.gov

Series of New Posts: Lectures, talks, podcasts, etc…

I will be starting a regular series of posts of lectures, talks, podcasts, etc. If you have requests for topics, please feel free to comment on this post or send me a message via the contact links. The first of these posts is below:

On Oct. 7, 2015, Perimeter Institute Director Neil Turok opened the 2015/16 season of the PI Public Lecture Series with a talk about the remarkably simplicity that underlies nature. Turok discussed how this simplicity at the largest and tiniest scales of the universe is pointing toward new avenues of physics research and could lead to revolutionary advances in technology.

Why a NASA spacecraft could bounce, crunch or sink on icy Europa

Why a NASA spacecraft could bounce, crunch or sink on icy Europa

Sometime in the early 2030s, NASA hopes to attempt a landing on Jupiter’s moon Europa. A four-legged spacecraft would descend towards the icy surface, ready to hunt for signs of alien life in a buried ocean.

Landing on Jupiter’s moon in search of alien life won’t be easy.

NewSpace NYC and NY Society of Security Analysts – A New Space Age Race: Interplanetary Investments

Three observations from tonight:
1) EVERYONE wants to be a leader but most are not visionaries.
2) A few are visionaries but lack the leadership, business skills and/or chutzpah to make it happen.
3) Then there are the very few with both vision and chutzpah to make it happen. But, they are not just the Musks or Bezoses, they are the smaller pioneers, some of whom I met tonight, and they are the key for getting to and crossing the tipping point to a vibrant commercial space industry/economy.

Possible signature of dark matter annihilation detected

A false-color image of the anomalous gamma-ray emission from the central region of the Milky Way galaxy; this emission is suspected of coming from dark matter annihilation. In this image, the emission from conventional sources has been subtracted from the total. The region covers roughly five degrees; the brightest emission is colored red and faintest blue.

CfA astronomer Doug Finkbeiner and a team of colleagues claim to have identified just such a signature of dark matter annihilation.

Earth might have hairy dark matter

The solar system might be a lot hairier than we thought. A new study publishing this week in the Astrophysical Journal by Gary Prézeau of NASA’s Jet Propulsion Laboratory, Pasadena, California, proposes the existence of long filaments of dark matter, or “hairs.”
