New research suggests that dark comets, which make up up to 60% of near-Earth objects, may originate in the asteroid belt and may carry subsurface ice that may have contributed to Earth’s water. Credit: SciTechDaily.com Research from the University of Michigan shows that as many as 60% of objects near Earth are dark comets. These … Read more
Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left), similar to Jupiter’s moon Europa, or an icy world with a liquid substellar ocean and a cloudy atmosphere (center). LHS 1140 b is 1.7 times the size of Earth (right) and is the most promising exoplanet in the habitable zone found … Read more
An exoplanet in its star’s habitable Goldilocks zone is now suspected of having a liquid water ocean and an atmosphere. The planet, called LHS 1140 b, is about 1.7 times the size of Earth and is located about 48 light-years away. This distant world, first discovered in 2017, now turns out to be a rocky … Read more
NASA has captured photos and videos of the two massive asteroids that passed by our planet a few weeks ago. The two asteroids, 2011 UL21 and 2024 MK, passed by Earth on June 27 and 29 respectively and were captured by NASA’s Deep Space Network’s Goldstone planetary radar. While 2011 UL21 flew past us at … Read more
Researchers using the James Webb Space Telescope have studied the interaction of a quasar with satellite galaxies, gaining crucial insights into the growth of galaxies in the early universe, the mass of black holes, and chemical evolution.

Researchers investigated three mysterious objects in the early universe. Shown here are their color images, compiled from three NIRCam filter bands aboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the name “little red dots”), with some evidence of spatial structure at blue wavelengths.

Artist’s impression of the bright core region of a quasar, an active galaxy. The supermassive black hole at the center is surrounded by a bright disk of gas and dust. The dust component further away can obscure the view of the interior and shines mainly in the mid-infrared range, light that can be analyzed by … Read more
Astronomers have discovered that our galaxy may be bigger than we first thought. A new model of the Milky Way has revealed that our galaxy is wider than we thought, according to a new paper in the journal Natural astronomy. The researchers found that the bulge at the center of our galaxy is less densely … Read more
Neutron stars are among the densest objects in the universe. The material inside them is so tightly compressed that scientists don’t yet know what shape it takes. The core of a neutron star may be a thick soup of quarks, or it may contain exotic particles that could not survive anywhere else in the universe. … Read more
Researchers have linked the periodic pulses of neutron stars to internal disturbances influenced by superfluid vortices. A new model suggests that these disturbances follow a power-law pattern observed in several natural phenomena. Credit: SciTechDaily.com A recent study has revealed the origin of the mysterious “heartbeats” observed in neutron stars, linking them to disturbances caused by … Read more
