Atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

Stars form in regions of space known as stellar nurseries, where high concentrations of gas and dust coalesce to form a baby ...

Also called molecular clouds, they can be massive, spanning hundreds of light-years and forming thousands of stars.

Stars are born in dense molecular clouds, but did they always form this way? Recent research suggests that in the early ...

Using the Hubble Space Telescope (HST), astronomers have observed a supermassive galactic open cluster designated Westerlund ...

Stars emerge from vast regions of gas and dust known as molecular clouds. These stellar nurseries, often spanning hundreds of ...

Could our solar system have been temporarily exposed to an enhanced flux of cosmic-rays at some point in the ancient past?

The possibly new formation is located 450 light-years away in the Taurus Molecular Cloud. HH 30 is a Herbig-Haro object, a small, radiant nebula nestled in a star-forming region. Such a phenomenon ...

a key ingredient in the formation of stars and planets. Unlike Earthly dust, this celestial material consists of silicates and carbon, playing a crucial role in cooling gas clouds and sparking new ...

Some fast-moving stars within the Milky Way have been traced back to the Large Magellanic Cloud (LMC). In a preprint paper that has not yet completed peer review, the astronomers who demonstrated ...
