Zdenek Sekanina, an astronomer with La Canada Flintridge in the U.S., reports what he describes as evidence of a possible breakup of comet Tsuchinshan prior to swinging around the sun. Sekanina specializes in comet behavior, ...
One could argue that brown dwarfs don't get the love they deserve. Sometimes referred to as "failed stars," they don't have enough mass to sustain nuclear fusion, which powers all stars, including our sun. But they are also ...
Susan Solomon, MIT professor of Earth, atmospheric, and planetary sciences (EAPS) and of chemistry, played a critical role in understanding how a class of chemicals known as chlorofluorocarbons were creating a hole in the ...
Two recent studies published in The Astrophysical Journal discuss findings regarding solar flare properties and a new classification index and the sun's magnetic field, specifically what's called solar magnetic reconnection.
A research team from the University Alliance Ruhr, Germany, has found a catalyst that can be used to convert ammonia into the energy carrier hydrogen and the fertilizer precursor nitrite. The production of hydrogen and the ...
Black holes are remarkable astronomical objects with gravity so strong that nothing, not even light, can escape them. The most gigantic ones, known as "supermassive" black holes, can weigh millions to billions times the mass ...
So far this summer, New York City—like much of the country—has clocked more than 11 90-plus degree days. In addition to the increasing frequency of extreme heat waves, if it seems hotter in the city than in other environments, ...
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly ...
A planet relatively close to Earth could be the first ever detected with a potentially life-sustaining liquid ocean outside our Solar System, according to scientists using the James Webb space telescope.
