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.

Washington, D.C. – NASA’s Kepler mission has verified 1,284 new planets — the single largest finding of planets to date.
“This announcement more than doubles the number of confirmed planets from Kepler,” said Ellen Stofan, chief scientist at NASA Headquarters in Washington. “This gives us hope that somewhere out there, around a star much like ours, we can eventually discover another Earth.”
Analysis was performed on the Kepler space telescope’s July 2015 planet candidate catalog, which identified 4,302 potential planets. For 1,284 of the candidates, the probability of being a planet is greater than 99 percent – the minimum required to earn the status of “planet.”

Moffett Field, CA – An instrument onboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) detected atomic oxygen in the atmosphere of Mars for the first time since the last observation 40 years ago. These atoms were found in the upper layers of the Martian atmosphere known as the mesosphere.
Atomic oxygen affects how other gases escape Mars and therefore has a significant impact on the planet’s atmosphere. Scientists detected only about half the amount of oxygen expected, which may be due to variations in the Martian atmosphere.«Read the rest of this article»

Washington, D.C. – NASA will host a news teleconference at 10:00am PDT (12:00pm CDT) Tuesday, May 10th to announce the latest discoveries made by its planet-hunting mission, the Kepler Space Telescope.
When Kepler was launched in March 2009, scientists did not know how common planets were outside our solar system. Thanks to Kepler’s treasure trove of discoveries, astronomers now believe there may be at least one planet orbiting every star in the sky.

Greenbelt, MD – A powerful combination of observations and computer simulations is giving new clues to how the moon got its mysterious “tattoos” — swirling patterns of light and dark found at over a hundred locations across the lunar surface.
“These patterns, called ‘lunar swirls,’ appear almost painted on the surface of the moon,” said John Keller of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “They are unique; we’ve only seen these features on the moon, and their origin has remained a mystery since their discovery.” Keller is project scientist for NASA’s Lunar Reconnaissance Orbiter (LRO) mission, which made the observations.

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.
NASA selects Pluto Orbiter, Extreme Environments Rover and 11 other pioneering technologies for development

Washington, D.C. – NASA has selected 13 proposals through NASA Innovative Advanced Concepts (NIAC), a program that invests in transformative architectures through the development of pioneering technologies.
Among the selected are: a concept for reprogramming microorganisms that could use the Martian environment to recycle and print electronics; a two-dimensional spacecraft with ultra-thin subsystems that may wrap around space debris to enable de-orbiting; and a method of computational imaging that leverages extrasolar intensity fluctuations to detect “echoes” from planets and other structures orbiting a distant star.
NASA’s Kepler Space Telescope given new mission to discover exoplanets in the center of Milky Way Galaxy
Written by Whitney Clavin
Pasadena, CA – Astronomers have made great strides in discovering planets outside of our solar system, termed “exoplanets.” In fact, over the past 20 years more than 5,000 exoplanets have been detected beyond the eight planets that call our solar system home.
The majority of these exoplanets have been found snuggled up to their host star completing an orbit (or year) in hours, days or weeks, while some have been found orbiting as far as Earth is to the sun, taking one Earth year to circle.

Pasadena, CA – The brilliant flash of an exploding star’s shockwave — what astronomers call the “shock breakout” — has been captured for the first time in visible light by NASA’s planet-hunter, the Kepler space telescope.
An international science team led by Peter Garnavich, an astrophysics professor at the University of Notre Dame in Indiana, analyzed light captured by Kepler every 30 minutes over a three-year period from 500 distant galaxies, searching some 50 trillion stars. They were hunting for signs of massive stellar death explosions known as supernovae.
