Latest Abraham (Avi) Loeb Stories
Dark matter, the mysterious substance that comprises more than 85 percent of the universe, is unlikely to be made of primordial black holes due to the existence of neutron stars.
Extremely quick, extremely bright radio pulses known as “fast radio bursts” may originate from flaring stars located within our own galaxy, researchers from the Harvard-Smithsonian Center for Astrophysics claim in a new study.
Harvard-Smithsonian Center for Astrophysics theorist Avi Loeb says that modern time is not the ideal scenario to study the universe, but rather about 13 billion years ago was.
In a new paper, researchers from Harvard-Smithsonian Center for Astrophysics and Princeton suggest a new technique for finding aliens: look for their city lights.
New calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may wander the Milky Way.
Astronomers are hunting an elusive target: rogue black holes that have been ejected from the centers of their home galaxies.
Astronomers have proposed an improved method of searching for intelligent extraterrestrial life using instruments like the one now under construction in Australia. This instrument could detect Earth-like civilizations around any of the 1,000 nearest stars.
Researchers from NASA's Goddard Space Flight Center in Maryland believe they have captured traces of radiation from long-extinguished stars that were "born" during the universe's infancy.
Common wisdom holds that we can never see a black hole because nothing can escape it - not even light. Fortunately, black holes aren't completely black. As gas is pulled into a black hole by its strong gravitational force, the gas heats up and radiates. That radiation can be used to illuminate the black hole and paint its profile.
What did the very first stars look like? How did they live and die? Astronomers have ideas, but no proof. The first stars are so distant and formed so long ago that they are invisible to our best telescopes.
