Outer Space

After about a month of darkness, Hubble is back online and already collection impressive scientific data.

Retired NASA Engineers Return to Fix Hubble Telescope

The repaired space computer is back online and already beaming spectacular images of distant galaxies back to Earth

A new image of a powerful jet firing out of the black hole at the center of the radio galaxy Centaurus A, taken with the Event Horizon Telescope.

New Black Hole Image Shows Plasma Jets Blasting Into Space

Researchers say the new, detailed image of the black hole at the center of the Centaurus A galaxy could reveal how its jets formed

The plumes were first discovered in 2006 when the Cassini spacecraft spotted the geysers shooting water and other organic materials at high velocities hundreds of miles into space near the moon's south pole.

Could Methane-Spewing Microbes Be Living in the Depths of a Subsurface Ocean on Saturn’s Moon Enceladus?

The hot, chemical plumes could be produced by something similar to Earthly microscopic life forms that consume hydrogen and carbon, then burp up methane

Ingenuity releases its first aerial photos of its shadow cast across the Séítah terrain during its ninth flight.

Innovation for Good: Game Changers

NASA’s Ingenuity Helicopter Soars 2,000 Feet Through Martian Atmosphere in Its Ninth Successful Test Flight

The aerial trooper set new records for speed and distance, as well as stretched the capabilities of its navigation system

Astronomers used the Keck Observatory in Hawai'i to analyze what chemical building blocks made up the Comet 46/P Wirtanen.

Boozy Comet’s Mysterious Heat Source Offers Clues to How Planets Like Earth Obtain Water

The cosmic relic contains minerals from when the solar system first formed and high amounts of methanol

Mice pups were borne out of freeze-dried mice sperm that had been stored on the International Space Station for up to six years. Some of those mice and their offspring are pictured here.

After a Six-Year Sojourn in Space, Freeze-Dried Mice Sperm Produce Healthy Pups

Scientists say the finding supports the idea that genetic material can be shipped to other worlds to help establish a diversity of life

A newly discovered white dwarf star (right) is only slightly larger than the moon (left).

New Research

Incredibly Dense White Dwarf Star Packs the Mass of the Sun Into the Size of the Moon

Researchers say if the star was any more massive it would likely collapse under its own weight and explode

Data collected revealed that a neutron star twice as massive as the sun was swallowed up by a black hole nine times the size of the sun.

Astrophysicists Detect a Black Hole Gobbling Up a Neutron Star in Two Separate Events

Researchers spotted both events using sensors to locate ripples in spacetime that traveled 900 million years to reach Earth

The supernova SN2018zd (large white dot on the right) located 30 to 40 million light years away was first identified in 2018 and may be the first observed evidence of an electron-capture supernova.

First Observed Nearly a Thousand Years Ago, Scientists Finally Confirm Elusive Third Type of Supernova

The stellar explosion may explain an odd event documented by Chinese astronomers in 1054 C.E.

NASA just announced a partnership with Tide to figure out how to do laundry in space. Solving this problem will allow astronauts to stop throwing away their dirty clothes, which means some missions must ferry hundreds of pounds of clean clothes into space.

NASA Just Put Doing the Laundry on Astronauts’ Chore List

Dirty clothes are currently thrown away, requiring missions where weight is at a premium to bring many pounds of socks, shirts and underwear

An artist's rendering of the Earth and sun seen from space. Astronomers on Earth can detect other worlds when far away stars flicker as an orbiting planet passes in front of them, partly blocking our view. New research asks how many alien worlds might have been able to detect Earth in this way.

New Research

If Aliens Exist in These 1,700 Solar Systems, They Can Probably See Earth

Hypothetical alien astronomers orbiting these stars could have seen the sun’s light flicker as Earth passed in front of it

The bright red regions were thought to be caused by molecules known as tholins, or organic compounds that rain down onto the surface after cosmic rays or ultraviolet light interact with the methane in Pluto's surface and atmosphere.

Pluto’s Red Patches Are Mystifying Scientists

A new study suggests there’s more to the dwarf planet’s rust-colored deposits than meets the eye

Like the newly-identified 2014 UN271, the NEOWISE comet pictured here is a long-period comet originating in the Oort Cloud.

Giant Comet From the Oort Cloud Will Pass by the Sun in 2031

Astronomers used about 40 observations of the object, which is called 2014 UN271, to estimate its size and orbit

A radar image of Venus' largest block of crust, located in the planet's lowlands and identified by the authors of a new paper.

New Research

Venus May Still Be Geologically Active

Radar images of the planet’s surface suggest large sections of its crust appear to have moved in the geologically recent past

It’s considered one of the coldest and smallest exoplanets discovered so far.

This Neptune-Like Exoplanet May Have Water Clouds

Despite the possible presence of water vapor, TOI-1231 b is likely not habitable because of its size

This will be the first NASA mission to Venus since 1990.

Future of Space Exploration

With Two New Missions, NASA Announces Return to Venus by 2030

The projects, DAVINCI+ and VERITAS, will explore the planet’s past and Earth’s similarities with its sister planet

Streaked across Ganymede's surface are bright light-colored regions of ridges and grooves that overlap darker-colored terrains along the icy shell. The textured scar-like areas suggest that the moon's surface underwent extreme geologic changes over time.

NASA’s Juno Space Probe Zooms by Largest Moon in the Solar System

The flyby will be the closest any spacecraft has flown near Ganymede in over two decades

These baby bobtail squid going to the International Space Station for an experiment that examines whether space alters the symbiotic relationship between the squid and a bioluminescent bacterium that allows them to glow.

NASA Is Launching Tardigrades and Baby Squid Into Space

The experiments could help astronauts stay healthy and survive longer outside Earth’s atmosphere

A tiny piece of orbiting debris punched a five-millimeter-wide hole in the robotic arm's insulation.

Space Junk Hit a Robotic Arm on the International Space Station

The arm, called Canadarm2, remains functional and will continue with its next mission

Researchers found that the bears could withstand an impact of up to 900 meters per second and shock pressures of up to 1.14 gigapascals (GPa). Any higher than those speeds, the seemingly invincible water bears turned to mush.

Water Bears Can Survive Impact Speeds of 1,845 Miles Per Hour

Tardigrades thrive in a variety of extreme conditions, so researchers wanted to know if they could withstand simulated space landing impacts
