Update on the 7 Earth-sized planets orbiting nearby

A new study of the seven Earth-sized exoplanets around TRAPPIST-1 indicate that all 7 planets are extremely similar to each other in makeup, but potentially quite different from Earth.

Supermassive Black Holes Could get Even Larger

It is thought that the upper mass limit for galactic black holes is around 100 billion solar masses, but new research suggests the mass limit could be much higher - more than a million times greater than the largest galactic black holes.

SpaceX has launched its 50th previously flown rocket

Thursday evening SpaceX's Falcon 9 rocket was successfully launched for the 50th time. It has only been five years and a few days since they landed their first one.

Primordial black holes and dark matter

Astronomers are studying black holes that could have formed in the early universe, before stars and galaxies were born. Such primordial black holes (PBHs) could account for all or part of dark matter.

A Map of Mars' Entire Ancient River Systems

Three to four billion years ago, Mars did in fact have running rivers of water. Now, scientists have mapped out an entire ancient river system.

Dark storm on Neptune reverses direction

Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune (a storm, which is wider than the Atlantic Ocean) abruptly steer away from a likely death on the giant blue planet.

NASA Announces its Artemis Astronauts

NASA has announced the names of the 18 astronauts that make up the Artemis Team. A select few, and some international partners, will be going back to the Moon. The next man and first woman on the Moon are among the names.

Chernobyl Fungus as Protection against Space Radiation

The researchers say the melanin-containing fungus that thrives in Chernobyl could be used to create protective shields for future astronauts, it decreases radiation by at least 1.82 % and potentially up to 5.04 %.

There Are More Craters On The Moon Then We Think

Thanks to China’s Chang’e-1 and Chang’e-2 lunar orbiters, the number of known craters on the moon’s surface is now more than a dozen times larger than the 9,137 craters that are officially recognized.

A Mysterious Signal from Proxima Centauri

The signal appears to emanate from the direction of our neighboring star and cannot yet be dismissed as Earth-based interference, raising the very faint prospect that it is a transmission from extraterrestrial intelligence.

Radioactive elements may be key to exoplanet habitability

As it turns out, organic material, liquid water, sunlight and a large moon might not be enough to ensure an exoplanet’s habitability. It also may depend on whether enough radioactive elements are present in the planet’s core.

Mars rover data indicates ancient megafloods

Raging megafloods, likely triggered by the heat of a meteoritic impact, roared across Gale Crater near the equator of Mars some 4 billion years ago, creating gigantic sedimentary ripples visible today.

China's Chang'e-5 Probe Drops Off Moon Samples

A Chinese probe has delivered the first samples to be collected from the Moon in more than 40 years. The Chang’e-5 sample return capsule floated down to the snowy plains of Inner Mongolia.

SOFIA opens a new window on quasars and galactic evolution

Astronomers have now found a so-called “cold quasar” in which star formation has managed to continue even in the presence of a ravenous supermassive black hole. The team  studied a quasar 5.25 billion light years away.

New superhighway system discovered in the Solar System

Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. They could be used to send spacecraft to the far reaches of our planetary system.
