A new explanation for the solar system's radioactive elements suggests Earth-like planets might be found orbiting up to 50 ...

The comet is the third object ever confirmed to have entered our cosmic neighborhood from elsewhere in the galaxy. Space ...

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 ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." Astronomers have discovered that the solar system may be ...

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

If you've ever wondered why we are here, then you can thank Jupiter for part of the answer. A new study from Rice University suggests that if it weren't for the gas giant, the Earth would have ...

About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But ...

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

3I/ATLAS likely weighs more than 33 billion tons. The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say. A ...

Astronomers have spotted 3I/ATLAS, just the third interstellar object ever seen in our solar system. Bigger, faster, and possibly far older than ‘Oumuamua or Borisov, this icy traveler could help ...

Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system Jay ...
