Small, cool and sulfurous exoplanet may help write recipe for planetary formation

A surprising yellow haze of sulfur dioxide in the atmosphere of a gas "dwarf" exoplanet about 96 light years away from our own solar system makes the planet a prime target for scientists trying to understand how worlds are ...

Lone star state: Tracking a low-mass star as it speeds across the Milky Way

It may seem like the sun is stationary while the planets in its orbit are moving, but the sun is actually orbiting around the Milky Way galaxy at an impressive rate of about 220 kilometers per second—almost half a million ...

Euclid is finding free floating planets in Orion, too

There are likely millions of "rogue" or free-floating planets (FFPs) spread through the galaxy. These planets, which aren't big enough to become stars but also aren't beholden to a star's gravity, are some of the hardest ...

NASA considering an interstellar probe to study the heliosphere, the region of space influenced by the sun

The sun warms the Earth, making it habitable for people and animals. But that's not all it does, and it affects a much larger area of space. The heliosphere, the area of space influenced by the sun, is over a hundred times ...

Researchers discover Earth and space share the same turbulence

In a paper published in Geophysical Research Letters, researchers have discovered that the turbulence in the thermosphere exhibits the same physical laws as the wind in the lower atmosphere. Furthermore, wind in the thermosphere ...

Researcher suggests that gravity can exist without mass, mitigating the need for hypothetical dark matter

Dark matter is a hypothetical form of matter that is implied by gravitational effects that can't be explained by general relativity unless more matter is present in the universe than can be seen. It remains virtually as mysterious ...
