We’ve never met some of the Sun’s closest neighbors until now. In a new study, astronomers report the discovery of 95 objects known as brown dwarfs, many within a few dozen light-years of the Sun. They’re well outside the solar system, so don’t experience heat from the Sun, but still inhabit a... Read More

The ultraviolet spectral range is rich with information about the atmospheres of exosolar planets, star formation, supernovae, the circumgalactic medium, and much more. Two future flagship mission concepts, Habitable Exoplanet characterization (HabEx) and Large Ultraviolet/Optical/Infrared survey... Read More

Several years ago, planetary scientist Lynnae Quick began to wonder whether any of the more than 4,000 known planets beyond our solar system might resemble some of the watery moons around Jupiter and Saturn. Though some of these moons don’t have atmospheres and are covered in ice, they are... Read More

Life as we know it requires three ingredients: energy, organic molecules, and liquid water. Our search for life beyond Earth is a search for planets, dwarf planets, and moons that harbor substantial liquid water. We call these places “ocean worlds.”

Researchers on the NASA-funded Community Snow Observations (CSO) project recently found a new way to use data from citizen scientists. This project asks volunteer to measure the depth of the snow in mountain environments and uses those data to improve snowpack models.
Ryan Crumley measures snow depth in the White Mountains of New Hampshire.

Millions of miles from Earth lies a dusty, cold, desert world with a very thin atmosphere. You know this planet as Mars…but it hasn’t always been this way. There’s evidence that the Red Planet was much wetter and warmer, with a thicker atmosphere, billions of years ago. Could it also have supported... Read More

For several weeks in summer 2020, NASA’s STEREO had the solar system’s best view of the star Betelgeuse, revealing more unexpected dimming by the star.

Observations by NASA's Hubble Space Telescope are showing that the unexpected dimming of the supergiant star Betelgeuse was most likely caused by an immense amount of hot material ejected into space, forming a dust cloud that blocked starlight coming from Betelgeuse's surface.
