First Prototype ‘Sprites’ – Precursors to Eventual ‘StarChip’ Probes – Achieve Low Earth Orbit
San Francisco – July 26, 2017 – Breakthrough Starshot, a multi-faceted program to develop and launch practical interstellar space missions, successfully flew its first spacecraft – the smallest ever launched.
On June 23, a number of prototype “Sprites” – the world’s smallest fully functional space probes, built on a single circuit board – achieved Low Earth Orbit, piggybacking on OHB System AG’s ‘...
Many rock stars don’t like to play by the rules, and a cosmic one is no exception. A team of astronomers has discovered that an extraordinarily bright supernova occurred in a surprising location. This “heavy metal” supernova discovery challenges current ideas of how and where such super-charged supernovas occur.
Supernovas are some of the most energetic events in the Universe. When a massive star runs out of fuel, it can collapse onto itself and create a spectacular explosion that briefly outshines an entire galaxy, dispersing vital elements into...
Evolver social movement & the Hive to Thrive speaker series hosted Harvard University director of astronomy Avi Loeb for a wide ranging discussion. From the nature of scientific discovery to possible origins of FRBs (Fast Radio Bursts) emanating from the cosmic background radio noise. Produced by Sam Tabar...
"The world's most indestructible species, the tardigrade, an eight-legged micro-animal, also known as the water bear, will survive until the Sun dies, according to a new Oxford University collaboration."
"The new study published in Scientific Reports, has shown that the tiny creatures, will survive the risk of extinction from all astrophysical catastrophes, and be around for at least 10 billion years – far longer than the human race."
"Cambridge, MA - Two separate teams of scientists have identified major challenges for the development of life in what has recently become one of the most famous exoplanet systems, TRAPPIST-1. "
"The teams, both led by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., say the behavior of the star in the TRAPPIST-1 system makes it much less likely than generally thought, that planets there could support life."
"An Earth-sized planet next door: that was the startling announcement last August. Astronomers had found an exoplanet orbiting the sun’s closest stellar neigh- bor, a cool red dwarf star called Proxima Centauri (1). Even better, the nearby world orbited within its parent star’s habitable zone, meaning liquid water could exist on the planet’s surface, which raised the prospects for its harboring life."

Hannah Jang-Condell, our alum who received her Ph.D. in 2004, has been given tenure at the University of Wyoming. She is an Associate Professor in their Physics and Astronomy Department. She studies planet formation theory, protoplanetary disk models, extrasolar planets, computational astrophysics, astrobiology. Congratulations, Hannah!
In case you haven't already heard the news about Ryan Hickox - a former Harvard grad student - now tenured professor at Dartmouth! Ryan also is one of the first "house professors" in the house system that Dartmouth is expanding:
Astronomy Undergraduates in Ay100 Observational Astronomy course over spring break went on a trip. They traveled to the Desert Museum, University of Arizona mirror lab to see telescope mirrors being made, and to Whipple observatory to observe on the 1.2-m and 1.5-m telescope collecting data for their class project.
I am very sorry to report that our colleague Pat Thaddeus passed away this morning.
Pat was a highly influential teacher and astronomer for over 50 years, including the past 30 at the CfA. His interests were extremely broad, including pioneering work on the cosmic microwave background radiation, planetary atmospheres, and large-scale studies of star formation and galactic structure. He was one of the founders of the now flourishing field of astrochemistry. His elegant laboratory spectroscopy provided ironclad identifications of many new...
Congratulations to Astronomy graduate student, Xiawei Wang, was selected as one of the eight Harvard Horizons scholars. The symposium will take place on Wednesday, April 12, 2017 at 4:30PM in Sanders theater. Read more
"A new citizen-science project will rescue tens of thousands of potentially valuable cosmic images that are mostly dead to science and bring them fully back to life. Called Astronomy Rewind, the effort, which launches today (22 March 2017), will take photographs, radio maps, and other telescopic images that have been scanned from the pages of dusty old journals and place them in context in digital sky atlases and catalogs. Anyone will then be able to find them online and compare them with modern electronic data...

"As the Faculty of Arts and Sciences works to address a “concerning” lack of diversity in the body, some have turned to astronomy professor John A. Johnson’s efforts as an example of creating opportunities for historically underrepresented minorities.
Harvard Graduate student Marion Dierickx recent paper featured:
"The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way's spiral disk. New research by Harvard astronomers shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of our galaxy."
