Astronomers baffled by discovery of a bizarre 'inside out' solar system
A team of astronomers has identified a four-planet system orbiting the red dwarf star LHS 1903 that defies conventional expectations about how planets arrange themselves around their host stars. The ...
According to the new data, Jupiter's radius measures 71,488 kilometers (44,421 miles) at its equator, and the planet rises 66 ...
Every once in a while, the outer solar system reminds us that we've only discovered a negligible portion of it, and that the vast majority is still full of surprises. The latest example of this is a ...
The first few exoplanets were discovered in the early 1990s. But it wasn’t until the early 2000s, when astronomers began carrying out large-scale, long-term surveys of other stars, that we started to ...
The comet is the third object ever confirmed to have entered our cosmic neighborhood from elsewhere in the galaxy. Space telescopes and orbiters have been documenting the rare visit. A mysterious ...
It may not feel like it, but everything in the universe is in constant motion. Our Sun, with all its planets, orbits the center of the Milky Way, flying through the cosmos at around 450,000 miles per ...
Nothing manmade has reached further from Earth than the Voyager series of spacecraft. Hurtling away from the sun at 38,000 miles an hour, the duo have now traveled over 12 billion miles, with Voyager ...
Astronomers are reporting the detection of a large object entering our solar system, and it is causing quite the stir in the scientific community. But now a fourth and much larger object has been ...
New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...
Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...
