NASA’s Hubble, MAVEN Help Solve the Mystery of Mars’ Escaping Water

Mars was once a very wet planet as is evident in its surface geological features. Scientists know that over the last 3 billion years, at least some water went deep underground, but what happened to the rest? Now, NASA’s Hubble Space Telescope and MAVEN (Mars Atmosphere and Volatile Evolution) missions are helping unlock that mystery. […]

NASA Earth Scientists Take Flight, Set Sail to Verify PACE Satellite Data

From sea to sky to orbit, a range of vantage points allow NASA Earth scientists to collect different types of data to better understand our changing planet. Collecting them together, at the same place and the same time, is an important step used to verify the accuracy of satellite data. NASA’s Plankton, Aerosol, Cloud, ocean […]

NASA’s Webb Reveals Distorted Galaxy Forming Cosmic Question Mark

It’s 7 billion years ago, and the universe’s heyday of star formation is beginning to slow. What might our Milky Way galaxy have looked like at that time? Astronomers using NASA’s James Webb Space Telescope have found clues in the form of a cosmic question mark, the result of a rare alignment across light-years of […]

NASA, ESA Missions Help Scientists Uncover How Solar Wind Gets Energy

Since the 1960s, astronomers have wondered how the Sun’s supersonic “solar wind,” a stream of energetic particles that flows out into the solar system, continues to receive energy once it leaves the Sun. Now, thanks to a lucky lineup of a NASA and an ESA (European Space Agency)/NASA spacecraft both currently studying the Sun, they […]

Hubble Zooms into the Rosy Tendrils of Andromeda

Clusters of stars set the interstellar medium ablaze in the Andromeda Galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way’s closest major galaxy. It measures approximately 152,000 light-years across and, with almost the same mass as our home galaxy, is headed for a collision with the Milky Way in […]

Hubble Observes An Oddly Organized Satellite

Andromeda III is one of at least 13 dwarf satellite galaxies in orbit around the Andromeda galaxy, or Messier 31, the Milky Way’s closest grand spiral galactic neighbor. Andromeda III is a faint, spheroidal collection of old, reddish stars that appears devoid of new star formation and younger stars. In fact, Andromeda III seems to […]

NASA Discovers a Long-Sought Global Electric Field on Earth

An international team of scientists has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields. Known as the ambipolar electric field, scientists first hypothesized over 60 years ago that it drove atmospheric escape above Earth’s North and South Poles.
