Harvard astronomer Avi Loeb and collaborator Michael McLeod have just published new analysis of metallic "spherules" recovered from the Pacific.
Tiny Metal Spheres Recovered from Ocean Floor Likely Interstellar, Alien-Hunting Harvard Astronomer Says
Possible meteor remnants found below the waves are likely interstellar, Avi Loeb's team says, but other scientists think the conclusion is premature.
A team including Harvard astronomer Avi Loeb may have just found a trace of an interstellar object, which Loeb believes could be alien in origin.
A new study claims to definitively point to a natural origin for 'Oumuamua, but alien-hunting Harvard astronomer Avi Loeb is not convinced.
"I think it's going to be inconclusive, if not impossible to demonstrate conclusively," one physicist said of the possible interstellar comet.
The new concept for faster travel to other solar systems would see humanity take flight to the stars similar to how birds soar on Earth.
We Need to Intercept Our Next Interstellar Visitor to See If It's Artificial, Astronomers Say in New Study
A new study games out a mission to intercept an interstellar object in space and get a close-up look to see just what its made of.
The heliosphere is the gateway to interstellar space, and it's a very weird place that we're just beginning to understand.
The U.S. military confirmed an interstellar meteor identified by Harvard astronomer Avi Loeb and student Amir Siraj, and now the pair say they've found another.
Scientists estimate there are billions of free-floating planets in our galaxy, and we should investigate them for signs of "cosmic hitchhikers," one scientist has proposed.
Voyager 1 is in "a high-radiation environment that no spacecraft have flown in before,” so a mystery like this isn't unexpected, the mission's project manager said.
The meteor that crashed into the Pacific was confirmed to be interstellar by secret government data. Harvard astronomer Avi Loeb wants to recover it.
