NASA Planet Hunter Finds Earth-Size Habitable-Zone World

NASA''s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star''s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. Scientists confirmed the find, called TOI 700 d, using NASA''s Spitzer Space Telescope and have modeled the planet''s potential

Exoplanets

Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []

Planet Sizes and Locations in Our Solar System

NASA''s Juno spacecraft took three images of Jupiter''s Great Red on Feb. 12, 2019, that were used to create this color-enhanced view. At the time the images were taken, the spacecraft was between 16,700 miles (26,900

90 Years of Our Changing Views of Earth

Right: The first image of Earth taken by a planetary spacecraft, Galileo, as it made a return encounter with its home planet for a gravity assist. As planetary spacecraft became more sophisticated in the 1970s, some turned their cameras toward the Earth as they departed on their long voyages of exploration.

Planet Earth Through the Ages

Earth hasn''t always looked like the blue orb we know so well. The variety of contending creatures that have come and gone over billions of years, in a sense, paints a picture of the many planets Earth has been: a lava-covered rock with a poisonous atmosphere, an ocean world with the bare beginnings of microbial life, a steaming tropical riot of earth-shaking

NASA''s Kepler Mission Discovers Bigger, Older Cousin to Earth

"On the 20th anniversary year of the discovery that proved other suns host planets, the Kepler exoplanet explorer has discovered a planet and star which most closely resemble the Earth and our Sun," said John Grunsfeld, associate administrator of NASA''s Science Mission Directorate at the agency''s headquarters in Washington.

What Is Earth? (Grades K-4)

Earth is our home planet. Scientists think Earth formed billions of years ago. It is the third-closest planet to the sun. Only Mercury and Venus are closer. Earth''s parts – land, air, water and life – are always changing. NASA studies Earth to learn how it changes. Some of the changes are natural. Some are caused by humans. Scientists

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. Measurements from a suborbital

NASA Captures "EPIC" Earth Image

A NASA camera on the Deep Space Climate Observatory satellite has returned its first view of the entire sunlit side of Earth from one million miles away. This color image of Earth was taken by NASA''s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope.

Carbon Dioxide Fertilization Greening Earth, Study Finds

From a quarter to half of Earth''s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.. An international team of 32 authors from 24 institutions in eight countries led the effort, which involved using satellite

Daily Views of Earth Available on New NASA Website

NASA launched a new website Monday so the world can see images of the full, sunlit side of the Earth every day. The images are taken by a NASA camera one million miles away on the Deep Space Climate Observatory (DSCOVR), a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Air Force.

NASA''s Kepler Telescope Discovers First Earth-Size Planet in

"The discovery of Kepler-186f is a significant step toward finding worlds like our planet Earth," said Paul Hertz, NASA''s Astrophysics Division director at the agency''s headquarters in Washington.

NASA''s TESS Discovers Planetary System''s Second Earth-Size

Using data from NASA''s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet''s surface. The world is 95% Earth''s size and likely rocky. Astronomers previously discovered three planets in this system, called

Solar System Exploration

The solar system has eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. There are five officially recognized dwarf planets in our solar system: Ceres, Pluto, Haumea, Makemake, and Eris.
