The Sun’s gravitational pull extends out to more than 160 times farther than Neptune’s. (Image credit: Vadim Petrakov via Shutterstock) Is there a huge, undiscovered planet at the edge of the solar system? The concept has been around since Pluto…
Illustration of a giant molecular cloud (Image credit: NSF) Astronomers have discovered a colossal cloud of gas and dust that stretches for as much as 200 light years and is hidden in a poorly studied region of the Milky Way.…
(Image credit: NSF/AUI/NSF NRAO) A team of scientists led by the National Science Foundation’s Green Bank Observatory (NSF GBO) recently identified an unusually rare object known as a long-period radio transient (LPT), designated CHIME J1634+44. These objects resemble rotating radio…

Sunspots captured in 2014. Spots this size are difficult to detect on distant stars because they cause brightness variations that are too small to be interpreted as noise. However, a new approach may have just revealed a large spot on…
