The six curiosities that Brown and Batygin identified have elongated elliptical orbits whose perihelia (their ... below the plane of the Milky Way as our Sun orbits the center of the galaxy. "But some ...

For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical ...

The next Mars rovers may traverse the Red Planet with futuristic tires. NASA 's Glenn Research Center released imagery and footage from testing of a novel tire, called a shape memory alloy spring tire ...

There is an official date for the opposition of Mars, but that's not the only night to observe it. The Red Planet will actually be brighter three days earlier, when it's closer to Earth (a consequence ...

"Clearly there is something interesting going on." The Hubble Space Telescope image you see above is from last year, and it showcases several galaxies that inhabit a pocket of our universe roughly ...

That's because 2025 is not what astronomers call a "perihelic opposition," which is when Mars gets closest to Earth while near its closest point to the sun on its slightly elliptical orbit.

One day, however, the two galaxies may collide, forming a giant, egg-shaped elliptical galaxy. But that great merger won't happen for billions of years. Mark is an award-winning journalist and the ...

Star formation is usually nearly non-existent in large elliptical galaxies, which represent the final stage in galaxy evolution. Unlike spiral galaxies like the Milky Way, with their distinct ...

Mars is on the cusp of becoming bigger and brighter than at any point since 2022 as it comes into alignment with Earth and the sun. Have you noticed Mars has been getting brighter and redder in ...

While the general interval is around 26 months, some oppositions can be more closely spaced due to the elliptical nature of Mars's orbit. For instance, "perihelic oppositions," which occur when ...

"Andromeda looks like a transitional type of galaxy that's between a star-forming spiral and a sort of elliptical galaxy dominated by aging red stars," said Weisz. "We can tell it's got this big ...

These combined efforts have revealed a dynamic menagerie of rarer galaxy types within the cluster. The Antlia Cluster is dominated by two massive elliptical galaxies—NGC 3268 and NGC 3258.
