In Quest to Reach Alpha Centauri, Breakthrough Starshot Launches World’s Smallest Spacecraft

July 31, 2017

Press Release:

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...

The Last Survivors on Earth

July 14, 2017

"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."

PNAS article on Proxima Centauri b

June 28, 2017

"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."

Pat Thaddeus

April 28, 2017

Dear Colleagues,

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...

With Astronomy Rewind, Citizen Scientists Bring Zombie Astrophotos Back to Life

March 23, 2017


"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...
