Pasadena, CA – An international team of astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope has reported what may be the first intact planet found closely orbiting a white dwarf, the dense leftover of a Sun-like star, only 40% larger than Earth.
The Jupiter-size object, called WD 1856 b, is about seven times larger than the white dwarf, named WD 1856+534. It circles this stellar cinder every 34 hours, more than 60 times faster than Mercury orbits our Sun.
Pasadena, CA – NASA’s Cassini spacecraft radar data recently published research presents a new scenario to explain why some methane-filled lakes on Saturn’s moon Titan are surrounded by steep rims that reach hundreds of feet high. The models suggests that explosions of warming nitrogen created basins in the moon’s crust.
Titan is the only planetary body in our solar system other than Earth known to have stable liquid on its surface. But instead of water raining down from clouds and filling lakes and seas as on Earth, on Titan it’s methane and ethane – hydrocarbons that we think of as gases but that behave as liquids in Titan’s frigid climate.
Washington, D.C. – On its final flyby of Saturn’s largest moon in 2017, NASA’s Cassini spacecraft gathered radar data revealing that the small liquid lakes in Titan’s northern hemisphere are surprisingly deep, perched atop hills and filled with methane.
The new findings, published April 15th in Nature Astronomy, are the first confirmation of just how deep some of Titan’s lakes are (more than 300 feet, or 100 meters) and of their composition. They provide new information about the way liquid methane rains on, evaporates from and seeps into Titan – the only planetary body in our solar system other than Earth known to have stable liquid on its surface.

Pasadena, CA – No matter how cold your winter has been, it’s probably not as chilly as Mars. Check for yourself: Starting today, the public can get a daily weather report from NASA’s InSight lander.
This public tool includes stats on temperature, wind and air pressure recorded by InSight. Sunday’s weather was typical for the lander’s location during late northern winter: a high of 2 degrees Fahrenheit (-17 degrees Celsius) and low of -138 degrees Fahrenheit (-95 degrees Celsius), with a top wind speed of 37.8 mph (16.9 m/s) in a southwest direction.

Pasadena, CA – Saturn’s moon Titan may be nearly a billion miles away from Earth, but a recently published paper based on data from NASA’s Cassini spacecraft reveals a new way this distant world and our own are eerily similar. Just as the surface of oceans on Earth lies at an average elevation that we call “sea level,” Titan’s seas also lie at an average elevation.
This is the latest finding that shows remarkable similarities between Earth and Titan, the only other world we know of in our solar system that has stable liquid on its surface.

Washington, D.C. – NASA has selected two finalist concepts for a robotic mission planned to launch in the mid-2020s: a comet sample return mission and a drone-like rotorcraft that would explore potential landing sites on Saturn’s largest moon, Titan.
The agency announced the concepts Wednesday, following an extensive and competitive peer review process. The concepts were chosen from 12 proposals submitted in April under a New Frontiers program announcement of opportunity.

Pasadena, CA – Steps forward in the search for life beyond Earth can be as simple as sending a balloon into the sky. In one of the most unique and extensive eclipse observation campaigns ever attempted, NASA is collaborating with student teams across the U.S. to do just that.
A larger initiative, NASA’s Eclipse Balloon Project, led by Angela Des Jardins of Montana State University, is sending more than 50 high-altitude balloons launched by student teams across the U.S. to livestream aerial footage of the August 21st, 2017, total solar eclipse from the edge of space to NASA’s website.

Pasadena, CA – Saturn’s icy, ocean-bearing moon Enceladus may have tipped over in the distant past, according to recent research from NASA’s Cassini mission. Researchers with the mission found evidence that the moon’s spin axis — the line through the north and south poles — has reoriented, possibly due to a collision with a smaller body, such as an asteroid.
Examining the moon’s features, the team showed that Enceladus appears to have tipped away from its original axis by about 55 degrees — more than halfway toward rolling completely onto its side.

Pasadena, CA – NASA’s Opportunity Mars rover will drive down a gully carved long ago by a fluid that might have been water, according to the latest plans for the 12-year-old mission. No Mars rover has done that before.
The longest-active rover on Mars also will, for the first time, visit the interior of the crater it has worked beside for the last five years. These activities are part of a two-year extended mission that began October 1st, the newest in a series of extensions going back to the end of Opportunity’s prime mission in April 2004.
Opportunity launched on July 7th, 2003 and landed on Mars on January 24th, 2004 (PST), on a planned mission of 90 Martian days, which is equivalent to 92.4 Earth days.

Pasadena, CA – NASA’s Cassini spacecraft has found deep, steep-sided canyons on Saturn’s moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.
A new paper in the journal Geophysical Research Letters describes how scientists analyzed Cassini data from a close pass the spacecraft made over Titan in May 2013. During the flyby, Cassini’s radar instrument focused on channels that branch out from the large, northern sea Ligeia Mare.
