At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas.


Satellite data has confirmed the formation of Subtropical Storm Melissa. NASA's Terra Satellite provided a visible image the former Nor'easter turned subtropical storm off the coast of New England.


Astronomers at the University of California, Riverside, have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation.


For decades, astronomers have speculated that the space between stars may be populated by exosolar minor bodies -- comets and asteroids -- ejected from their home planetary systems.

The Copernicus Sentinel-2 mission takes us over two saline lakes in East Africa: the larger Lake Natron in northern Tanzania and the smaller Lake Magadi, just over the border in Kenya.


Mars may seem to be an alien world, but many of its features look eerily familiar - such as this ancient, dried-up river system that stretches out for nearly 700 kilometres across the surface, making it one of the longest valley networks on the planet.


The discovery of ice deposits in craters scattered across the Moon's south pole has helped to renew interest in exploring the lunar surface, but no one is sure exactly when or how that ice got there.


Typhoon Hagibis is headed towards Japan's main island of Honshu, where it is expected to make landfall over the weekend. Japan is bracing for potential damage from strong winds and torrential rain.


Our Milky Way is a frugal galaxy. Supernovas and violent stellar winds blow gas out of the galactic disk, but that gas falls back onto the galaxy to form new generations of stars.


Rocky exoplanets that are around Earth-size are comparatively small, which makes them incredibly difficult to detect and characterise using telescopes.


Submarine canyons are a final frontier on planet Earth.


Physicists at Stockholm University and the Max Planck Institute for Physics have turned to plasmas in a proposal that could revolutionise the search for the elusive dark matter.


Tuesday was packed with more spacewalk preparations along with ongoing microgravity research aboard the International Space Station. The six-member Expedition 61 crew also conducted emergency response training and cargo transfers from a Japanese cargo craft.

NASA's Terra satellite passed over the eastern North Atlantic Ocean early on Oct. 3 and captured a visible image of Post-tropical Cyclone Lorenzo as it neared Ireland. Lorenzo's eastern side is already affecting Ireland, and both Ireland and the United Kingdom have posted warnings today.


The shortening daylight and cooling temperatures of late summer triggers changes in the Northern Hemisphere--changes that can be viewed from space.


A team led by Carnegie's Scott S. Sheppard has found 20 new moons orbiting Saturn. This brings the ringed planet's total number of moons to 82, surpassing Jupiter, which has 79.


Eight briefcase-size satellites flying in a row may be key to improving forecasts of a hurricane's wind speed -- detecting whether it will make landfall as a Category 1 or a Category 5.


Super typhoon Hagibis formed quickly over the weekend of Oct. 5 and 6.


In this picture from Sept. 28, 2019, engineers and technicians working on the assembly and testing of the Mars 2020 spacecraft look on as a crane lifts the rocket-powered descent stage away from the rover.


The skies were clear, the winds were low, and the lasers aligned.


The two baby stars were found in the [BHB2007] 11 system - the youngest member of a small stellar cluster in the Barnard 59 dark nebula, which is part of the clouds of interstellar dust called the Pipe nebula.


The Netherlands is featured in this false-colour image captured by the Copernicus Sentinel-2 mission. This image was processed in a way that included the near-infrared channel, which makes vegetation appear bright red.


NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.


Nick Hague @AstroHague "From only a few hundred miles up, you can see an entire state. The human footprint fades and the blue, and turquoise waters around Florida draw you in. Here is where we will launch ourselves to the Moon during #Artemis, as we continue to explore the mysteries of our universe."


NASA's InSight lander, which is on a mission to explore the deep interior of Mars, positioned its robotic arm this past weekend to assist the spacecraft's self-hammering heat probe. Known as "the mole," the probe has been unable to dig more than about 14 inches (35 centimeters) since it began burying itself into the ground on Feb. 28, 2019.


NASA astronaut Nick Hague returned to Earth from the International Space Station on Thursday, alongside Soyuz commander Alexey Ovchinin of the Russian space agency Roscosmos and visiting astronaut Hazzaa Ali Almansoori from the United Arab Emirates (UAE).


The global climate crisis poses new risks to humanity, and with them, new challenges to the practices of professional astronomy.


Two Expedition 60 crewmates and a visiting astronaut are returning to Earth on Thursday. The orbiting Expedition 61 residents staying on the International Space Station will then turn their attention to a series of spacewalks set to begin this weekend.


A team of scientists from South Africa has discovered evidence partially supporting a hypothesis that Earth was struck by a meteorite or asteroid 12 800 years ago, leading to global consequences including climate change, and contributing to the extinction of many species of large animals at the time of an episode called the Younger Dryas.


Astronomers have uncovered two historic events in which the Andromeda Galaxy underwent major changes to its structure.


The International Space Station is gearing up for a record pace of spacewalks this year. The Expedition 61 spacewalkers will upgrade the orbiting lab's power systems and repair a cosmic particles detector. NASA TV will preview the upcoming spacewalks during a live briefing on Friday at 2 p.m. EDT.


Last night, NASA's Juno mission to Jupiter successfully executed a 10.5-hour propulsive maneuver -- extraordinarily long by mission standards.


Put an ear to the ground on Mars and you'll be rewarded with a symphony of sounds. Granted, you'll need superhuman hearing, but NASA's InSight lander comes equipped with a very special "ear."


Hurricane Lorenzo was heading toward the Azores Islands when NASA-NOAA's Suomi NPP satellite provided forecasters with an image of the storm. Satellite imagery revealed the large extent of the storm.
