Machine learning algorithms can find anomalous needles in cosmic haystacks
The face of astronomy is changing. Though narrow-field point-and-shoot astronomy still matters (JWST anyone?), large wide-field surveys promise to be the powerhouses of discovery in the coming decades, especially with the ...

Model suggests Milky Way warp and flare due to tilt of dark halo
A trio of astrophysicists with Harvard and Smithsonian's Center for Astrophysics has found via computer modeling that the likely reason for the warp and flare of the Milky Way galaxy is a tilt of the dark halo. In their paper ...
We can't see the first stars yet, but we can see their direct descendants
If you take a universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us. We are the descendants of the primeval elements. We are the cast-off dust of the first stars, and many generations ...

New Type I supernova discovered with JWST
Using the James Webb Space Telescope (JWST), an international team of astronomers has observed the galaxy cluster PLCK G165.7+67.0. The observational campaign resulted in the detection of a new Type I supernova. The finding ...
NASA team simulates a glimpse of our galaxy in gravitational waves
Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wave ...

Galaxies breathe gas, and when they stop, no more stars form
For most of the history of astronomy, all we could see were stars. We could see them individually, in clusters, in nebulae, and in fuzzy blobs that we thought were clumps of stars but were actually galaxies. The thing is, ...

When did the first exocontinents appear in the universe?
On Earth, continents are likely necessary to support life. Continents "float" on top of the Earth's viscous mantle, and heat from the planet's core keeps the mantle from solidifying and locking the continents into place.

A new observatory could spot core-collapse supernovae before they explode
The thing about a supernova is that you never know when it might occur. Supernovae are triggered either by a collision with another star or when the interior of a massive star becomes depleted of nuclear fuel and begins a ...
