Far away in the Ursa Major constellation is a swirling galaxy that would not look out of place on a coffee made by a starry-eyed barista....

On May 29, 2020, a family of sunspots--dark spots that freckle the face of the sun, representing areas of complex magnetic fields--sported the biggest solar flare since October 2017. Although the sunspots are not yet vis...

Astronomers have discovered a collisional ring galaxy that existed when the Universe was just 3 billion years old, a find which could have implications for our theories on galactic evolution. The post Rare “Ring Galaxy...

Two entirely different ways of "weighing" the cosmos are producing disparate results. The discrepancy could be a sign that physicists will need to revise the standard model of cosmology.

Musk's remark after SpaceX's first crewed launch on Saturday (May 30) references a 2014 barb by a top Russian official.

The first astronauts launched by SpaceX declared victory Monday in NASA's cosmic capture-the-flag game.

Scientists at the Center for Astrophysics | Harvard & Smithsonian, and the Black Hole Initiative (BHI), have shed light on how black holes grow over time by developing a new model to predict if growth by accretion or by ...

Harvard-Smithsonian Center for Astrophysics:

A team of researchers, led by astrophysicist Sumner Starrfield of Arizona State University, has combined theory with both observations and laboratory studies and determined that a class of stellar explosions, called clas...

Twin shock waves produced by the galaxy's central black hole could have inflated the gargantuan Fermi Bubbles about 6 million years ago, a new study suggests.

The 49ers who panned for gold during California's Gold Rush didn't really know where they might strike it rich. They had word of mouth and not much else to go on.

The first-ever orbital flight of astronauts on a private spacecraft has been a historic success --

Even as the Dark Energy Spectroscopic Instrument, or DESI, lies dormant within a telescope dome on a mountaintop in Arizona, due to the COVID-19 pandemic, the DESI project has moved forward in reaching the final formal a...

The halo that surrounds our own Milky Way galaxy is much hotter than scientists once believed--and it may not be unique among galaxies.

Physicists are figuring out how close you can get to a black hole before you are unlikely to escape. That threshold is called the innermost stable circular orbit (ISCO).

Astronomers using European Southern Observatory (ESO) telescopes have discovered giant spots on the surface of extremely hot stars hidden in stellar clusters. Not only are these stars plagued by magnetic spots, some also...

If we ever intend to send crewed missions to deep-space locations, then we need to come up with solutions for keeping the crews supplied. For astronauts aboard the International Space Station (ISS), who regularly receive...

Determined to find a needle in a cosmic haystack, a pair of astronomers time traveled through archives of old data from W. M. Keck Observatory on Mauankea in Hawaii and old X-ray data from NASA's Chandra X-ray Observator...

High-resolution images of the debris disks around stars are revealing how solar systems form --

An international team of astronomers has conducted spectroscopic and photometric observations of a binary star known as 7 Vulpeculae. The new study, described in a paper published May 22 on arXiv.org, discloses more info...

While carbon dioxide is more abundant in the atmosphere and therefore more commonly associated with global warming, methane is around 30 times more potent as a heat-trapping gas. Given its importance, Canadian company GH...
