Most of the energy and power used on Earth comes from burning fossil fuels. Combustion sparked the industrial revolution, and today it provides us with reliable power, clean water, a stable food supply and a whole lot more. Unfortunately, one downside of all that progress is pollution, which leads... Read More
A special type of aurora, draped east-west across the night sky like a glowing pearl necklace, is helping scientists better understand the science of auroras and their powerful drivers out in space.
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
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.
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.
NASA’s first asteroid-sampling spacecraft just completed its second successful sample collection rehearsal.
The Catalina Sky Survey has been collecting images of the night sky for over twenty years. Today you’ll have the chance of a lifetime---the chance to find a new TNO.
NASA's TESS has completed its primary mission, imaging about 75% of the starry sky during a two-year-long survey. TESS has found 66 new planets, nearly 2,100 candidates, and much more.
After launching laser beams for years to NASA's Moon orbiter, scientists receive signal back for the first time.
Mystery Solved: Bright Areas on Ceres Come From Salty Water Below
Helium is the second most abundant element in the universe after hydrogen. But scientists aren’t sure just how much there actually is in the Sun’s atmosphere. NASA's HERSCHEL sounding rocket has taken the first global measurements of helium in the extended solar atmosphere – a key piece of... Read More
Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA’s MAVEN spacecraft. The results are being used to illuminate complex circulation patterns in the Martian atmosphere.
Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions.
The spacecraft may have found where the colorless gas has been hiding on the solar system's biggest planetary inhabitant.
