Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a very different structure than comets in the solar system.
The country’s newly formed space agency wants to establish a lunar base by 2045.
A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of conventional astronomy theory, and is making experts reconsider conventional notions of planet formation.
Recent flybys of the fiery world refute a leading theory of its inner structure—and reveal how little is understood about geologically active moons.
The Tianwen-2 probe has sent a self-portrait as it heads toward one of the most enigmatic objects in our space neighborhood: the quasi-moon Kamo’oalewa.
Using a neural network trained with simulations of supermassive black holes, astronomers have found that the one at the center of the Milky Way, Sagittarius A*, likely rotates at maximum speed.
Researchers estimate that MoM z14 was created 280 million years after the Big Bang, 10 million years earlier than the previous most primitive galaxy recorded.
Based on 20 years of observations by NASA’s Hubble Space Telescope, new research sheds light on one of the solar system’s most mysterious planets.
Galactic bones, filaments of radio-wave-emitting particles, run through our galaxy, and one of them has a fracture. New analysis suggests collision with a neutron star may have caused it.
By understanding the churning region near singularities, physicists hope they might be able to reconcile gravity and quantum mechanics.
