Washington, D.C. – For the first time in history, NASA astronauts have launched from American soil in a commercially built and operated American crew spacecraft on its way to the International Space Station. The SpaceX Crew Dragon spacecraft carrying NASA astronauts Robert Behnken and Douglas Hurley lifted off at 2:22pm CDT Saturday on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
“Today a new era in human spaceflight begins as we once again launched American astronauts on American rockets from American soil on their way to the International Space Station, our national lab orbiting Earth,” said NASA Administrator Jim Bridenstine.
Washington, D.C. – NASA has captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning a distance of more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.
Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.
NASA Researchers are developing new technologies to discover Earth-like Planets beyond our Solar System

Pasadena, CA – We humans might not be the only ones to ponder our place in the universe. If intelligent aliens do roam the cosmos, they too might ask a question that has gripped humans for centuries: Are we alone?
These aliens might even have giant space telescopes dedicated to studying distant planets and searching for life. Should one of those telescopes capture an image of our blue marble of a planet, evidence of forests and plentiful creatures would jump out as simple chemicals: oxygen, ozone, water and methane.

Pasadena, CA – In a nod to extraterrestrial mountaineers of the future, scientists working on NASA’s Cassini mission have identified the highest point on Saturn’s largest moon, Titan.
Titan’s tallest peak is 10,948 feet (3,337 meters) high and is found within a trio of mountainous ridges called the Mithrim Montes. The researchers found that all of Titan’s highest peaks are about 10,000 feet (3,000 meters) in elevation. The study used images and other data from Cassini’s radar instrument, which can peer through the obscuring smog of Titan’s atmosphere to reveal the surface in detail.

Pasadena, CA – New, detailed maps of the world’s natural landscapes created using NASA satellite data could help scientists better predict the impacts of future climate change.
The maps of forests, grasslands and other productive ecosystems provide the most complete picture yet of how carbon from the atmosphere is reused and recycled by Earth’s natural ecosystems.
Scientists at the University of Edinburgh, Scotland, United Kingdom; NASA’s Jet Propulsion Laboratory, Pasadena, California; and Wageningen University, Netherlands, used a computer model to analyze a decade of satellite and field study data from 2001 to 2010.

Pasadena, CA – Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system.
The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun.
The researchers, Konstantin Batygin and Mike Brown, discovered the planet’s existence through mathematical modeling and computer simulations but have not yet observed the object directly.
NASA’s Spitzer and Kepler space telescopes discover star with storm cloud similar to Jupiter’s Red Spot

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.
Pasadena, CA – Mars is blanketed by a thin, mostly carbon dioxide atmosphere — one that is far too thin to keep water from freezing or quickly evaporating. However, geological evidence has led scientists to conclude that ancient Mars was once a warmer, wetter place than it is today.
To produce a more temperate climate, several researchers have suggested that the planet was once shrouded in a much thicker carbon dioxide atmosphere. For decades that left the question, “Where did all the carbon go?”
The solar wind stripped away much of Mars’ ancient atmosphere and is still removing tons of it every day. But scientists have been puzzled by why they haven’t found more carbon — in the form of carbonate — captured into Martian rocks. They have also sought to explain the ratio of heavier and lighter carbons in the modern Martian atmosphere.

Pasadena, CA – With just one year remaining in a five-year trek to Jupiter, the team of NASA’s Juno mission is hard at work preparing for the spacecraft’s expedition to the solar system’s largest planet.
The mission aims to reveal the story of Jupiter’s formation and details of its interior structure. Data from Juno will provide insights about our solar system’s beginnings, and what we learn from the mission will also enrich scientists’ understanding of giant planets around other stars.

Pasadena, CA – A school of sardines fluttered by as giant leafy kelp swayed back and forth at the California Science Center in Los Angeles on Monday, June 22nd. At the bottom of this 188,000-gallon aquatic tank, a bright orange garibaldi fish seemed to ignore a new visitor to the aquatic wonderland: the silver body of an under-ice rover.
The rover’s presence 24 feet (7.3 meters) underwater at the science center this week helped researchers at NASA’s Jet Propulsion Laboratory, Pasadena, California, test the innovative rover’s systems. On Monday, the visitors’ guide to the rover and the fish around it was Andy Klesh, principal investigator for the rover at JPL and volunteer diver at the science center.
