Greenbelt, MD – Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research published in The Astrophysical Journal. This first look at relatively small features, dubbed “plumelets,” could help scientists understand how and why disturbances form in the solar wind.
The Sun’s magnetic influence stretches billions of miles, far past the orbit of Pluto and the planets, defined by a driving force: the solar wind.
Greenbelt, MD – Only the two Voyager spacecraft have ever been there, and it took than more than 30 years of supersonic travel. It lies well past the orbit of Pluto, through the rocky Kuiper belt, and on for four times that distance. This realm, marked only by an invisible magnetic boundary, is where Sun-dominated space ends: the closest reaches of interstellar space.
In this stellar no-man’s land, particles and light shed by our galaxy’s 100 billion stars jostle with ancient remnants of the big bang. This mixture, the stuff between the stars, is known as the interstellar medium. Its contents record our solar system’s distant past and may foretell hints of its future.
Washington, D.C. – For the first time, a spacecraft has sent back pictures of the sky from so far away that some stars appear to be in different positions than we’d see from Earth.
More than four billion miles from home and speeding toward interstellar space, NASA’s New Horizons has traveled so far that it now has a unique view of the nearest stars.
“It’s fair to say that New Horizons is looking at an alien sky, unlike what we see from Earth,” said Alan Stern, New Horizons principal investigator from Southwest Research Institute (SwRI) in Boulder, Colorado.
Washington, D.C. – When the New Horizons spacecraft passed by Pluto in 2015, one of the many fascinating features its images revealed was that this small, frigid world in the distant solar system has a hazy atmosphere. Now, new data help
Remote observations of Pluto by NASA’s telescope on an airplane, the Stratospheric Observatory for Infrared Astronomy, or SOFIA, show that the thin haze enshrouding Pluto is made of very small particles that remain in the atmosphere for prolonged periods of time rather than immediately falling to the surface.
Greenbelt, MD – NASA says a new spacecraft is journeying to the Sun to snap the first pictures of the Sun’s north and south poles.
Solar Orbiter, a collaboration between the European Space Agency, or ESA, and NASA, will have its first opportunity to launch from Cape Canaveral on February 7th, 2020, at 10:15pm CST.
Launching on a United Launch Alliance Atlas V rocket, the spacecraft will use Venus’s and Earth’s gravity to swing itself out of the ecliptic plane — the swath of space, roughly aligned with the Sun’s equator, where all planets orbit.
Washington, D.C. – In the vast garden of the universe, the heaviest black holes grew from seeds states NASA. Nourished by the gas and dust they consumed, or by merging with other dense objects, these seeds grew in size and heft to form the centers of galaxies, such as our own Milky Way.
But unlike in the realm of plants, the seeds of giant black holes must have been black holes, too. And no one has ever found these seeds – yet.
Washington, D.C. – Saturn’s moon Titan will be the next destination for NASA in our solar system. Titan is the unique, richly organic world. Advancing our search for the building blocks of life, the Dragonfly mission will fly multiple sorties to sample and examine sites around Saturn’s icy moon.

Pasadena, CA – According to NASA, the mystery of why Earth has so much water, allowing our “blue marble” to support an astounding array of life, is clearer with new research into comets.
Comets are like snowballs of rock, dust, ice, and other frozen chemicals that vaporize as they get closer to the Sun, producing the tails seen in images.
A new study reveals that the water in many comets may share a common origin with Earth’s oceans, reinforcing the idea that comets played a key role in bringing water to our planet billions of years ago.
Greenbelt, MD – Much has changed technologically since NASA’s Galileo mission dropped a probe into Jupiter’s atmosphere to investigate, among other things, the heat engine driving the gas giant’s atmospheric circulation.
A NASA scientist and his team at the Goddard Space Flight Center in Greenbelt, Maryland, are taking advantage of those advances to mature a smaller, more capable net flux radiometer. This type of instrument tells scientists where heating and cooling occurs in a planet’s atmosphere and defines the roles of solar and internal heat sources that contribute to atmospheric motions.

Greenbelt, MD – Every object, planet or person traveling through space has to contend with the Sun’s damaging radiation — and the Moon has the scars to prove it.
Research using data from NASA’s ARTEMIS mission — short for Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun — suggests how the solar wind and the Moon’s crustal magnetic fields work together to give the Moon a distinctive pattern of darker and lighter swirls.
