Pasadena, CA – Astronomers have discovered the youngest fully formed exoplanet ever detected. The discovery was made using NASA’s Kepler Space Telescope and its extended K2 mission, as well as the W. M. Keck Observatory on Mauna Kea, Hawaii. Exoplanets are planets that orbit stars beyond our sun.
The newfound planet, K2-33b, is a bit larger than Neptune and whips tightly around its star every five days. It is only 5 to 10 million years old, making it one of a very few newborn planets found to date.

Chicago, IL – The four planets of the Kepler-223 star system appeared to have little in common with the planets of our own solar system today. But a new study using data from NASA’s Kepler space telescope suggests a possible commonality in the distant past.
The Kepler-223 planets orbit their star in the same configuration that Jupiter, Saturn, Uranus and Neptune may have had in the early history of our solar system, before migrating to their current locations.

Moffett Field, CA – Dwarf planets tend to be a mysterious bunch. With the exception of Ceres, which resides in the main asteroid belt between Mars and Jupiter, all members of this class of minor planets in our solar system lurk in the depths beyond Neptune.
They are far from Earth – small and cold – which makes them difficult to observe, even with large telescopes. So it’s little wonder astronomers only discovered most of them in the past decade or so.
Pluto is a prime example of this elusiveness. Before NASA’s New Horizons spacecraft visited it in 2015, the largest of the dwarf planets had appeared as little more than a fuzzy blob, even to the keen-eyed Hubble Space Telescope.

Pasadena, CA – During a recent stargazing session, NASA’s Cassini spacecraft watched a bright star pass behind the plume of gas and dust that spews from Saturn’s icy moon Enceladus. At first, the data from that observation had scientists scratching their heads. What they saw didn’t fit their predictions.
The observation has led to a surprising new clue about the remarkable geologic activity on Enceladus: It appears that at least some of the narrow jets that erupt from the moon’s surface blast with increased fury when the moon is farther from Saturn in its orbit.

Moffett Field, CA – NASA mission operations engineers have successfully recovered the Kepler spacecraft from Emergency Mode (EM). On Sunday morning, the spacecraft reached a stable state with the communication antenna pointed toward Earth, enabling telemetry and historical event data to be downloaded to the ground. The spacecraft is operating in its lowest fuel-burn mode.
The mission has cancelled the spacecraft emergency, returning the Deep Space Network ground communications to normal scheduling.
Washington, D.C. – A year ago, Pluto was just a bright speck in the cameras of NASA’s approaching New Horizons spacecraft, not much different than its appearances in telescopes since Clyde Tombaugh discovered the then-ninth planet in 1930.
But this week, in the journal Science, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby.

Pasadena, CA – NASA has selected 28 researchers as participating scientists for the Curiosity Mars rover mission, including six newcomers to the rover’s science team.
The six new additions work in Alabama, Colorado, Indiana, Pennsylvania, Michigan and Tennessee. Eighty-nine scientists around the world submitted research proposals for using data from Curiosity and becoming participating scientists on the Mars Science Laboratory Project, which built and operates the rover.
NASA’s Spitzer and Kepler space telescopes discover star with storm cloud similar to Jupiter’s Red Spot
Written by Whitney Clavin
Pasadena, CA – Astronomers have discovered what appears to be a tiny star with a giant, cloudy storm, using data from NASA’s Spitzer and Kepler space telescopes. The dark storm is akin to Jupiter’s Great Red Spot: a persistent, raging storm larger than Earth.
“The star is the size of Jupiter, and its storm is the size of Jupiter’s Great Red Spot,” said John Gizis of the University of Delaware, Newark. “We know this newfound storm has lasted at least two years, and probably longer.” Gizis is the lead author of a new study appearing in The Astrophysical Journal.

Washington, D.C. – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today.
MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. The findings reveal that the erosion of Mars’ atmosphere increases significantly during solar storms. The scientific results from the mission appear in the November 5th issues of the journals Science and Geophysical Research Letters.

Washington, D.C. – Imagine a world with extreme temperatures that can wreak havoc on unprotected spacecraft and habitat components; a world where water is so scarce that plants are outfitted with sensors so farmers can avoid overwatering them; a world where precious water supplies are found in underground oases by satellites in orbit; a world where systems filter, recycle and purify air for the survival of inhabitants huddled in shelters.
Although images of human habitation on Mars may have filled your mind, the world just described is actually Earth, and the technologies cited are spinoffs, or technologies developed by the American space program that have gone on to benefit the public.
