Avi Loeb's lated Scientific American blog post explores the idea that, "A civilization in the habitable zone of a dwarf star like Proxima Centauri might find it hard to get into interstellar space with conventional rockets."
"Are we alone? This is surely a question each and every one of us has asked, at some point in our lives. And while most of us go no further than simply putting this question out there, there are people who feel compelled to devote time and effort in a bid to find the answer. Today our guest on Sputnik's Weekend Special is just such a man - Abraham Loeb, Professor of Astronomy at Harvard University and an adviser to the Breakthrough Listen project."
"It’s a long shot, but scientists are about to listen very closely for radio signals from our solar system’s first known interstellar visitor." "Ever since its discovery in mid-October as it passed by Earth already outbound from our solar system, the mysterious object dubbed ‘Oumuamua (Hawaiian for “first messenger”) has left scientists utterly perplexed."
The Harvard Crimson recently profiled one of the Astronomy Department's undergraduates, Eden Girma. Eden is pursuing a joint concentration in Mathematics and Astrophysics and is currently working on her Senior Thesis with Department Chair Avi Loeb.
"It’s impossible to miss when the seasons change. But do most people understand the science behind those changes? According to decades-old research by astronomers and educators at the Harvard-Smithsonian Center for Astrophysics (CfA), probably not."
"Somewhere in the neighborhood of the red dwarf star Proxima Centauri—4.25 light years from Cambridge—a small, hyper-reflective spacecraft will home in on an unfamiliar planet." Full article in the Harvard Crimson
For thousands of years, humans have searched for a way to turn matter into gold. Ancient alchemists considered this precious metal to be the highest form of matter. As human knowledge advanced, the mystical aspects of alchemy gave way to the sciences we know today. And yet, with all our advances in science and technology, the origin story of gold remained unknown. Until now.
Marking the beginning of a new era in astrophysics, scientists have detected gravitational waves and electromagnetic radiation, or light, from the same event for the first time. This historic discovery reveals the merger of two neutron stars, the dense cores of dead stars, and resolves the debate about how the heaviest elements such as platinum and gold were created in the Universe.
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...
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...
"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."
