NASA Scientists train in Nevada Desert to remotely control Mars Perseverance Rover

May 7, 2020 |

Pasadena, CA – Billions of years ago, the Martian surface could have supported microbial life as we know it. But did such life ever actually exist there? NASA and its Mars 2020 mission hope to find out with the Perseverance rover, which launches to the Red Planet this summer.

Scientists have sought answers to astrobiological questions on Earth, studying regions similar enough to Mars to understand what the Red Planet’s microscopic fossil record might look like. One research trip late last year involved fossilized microbes in the Australian Outback.

NASA’s Hubble Space Telescope observations gives clues to makeup of Super Puffy Planets

January 5, 2020 |

Greenbelt, MD – New data from NASA’s Hubble Space Telescope have provided the first clues to the chemistry of two of these super-puffy planets, which are located in the Kepler 51 system. This exoplanet system, which actually boasts three super-puffs orbiting a young Sun-like star, was discovered by NASA’s Kepler space telescope in 2012.

However, it wasn’t until 2014 when the low densities of these planets were determined, to the surprise of many.

The recent Hubble observations allowed a team of astronomers to refine the mass and size estimates for these worlds — independently confirming their “puffy” nature.

This illustration depicts the Sun-like star Kepler 51 and three giant planets that NASA’s Kepler space telescope discovered in 2012–2014. These planets are all roughly the size of Jupiter but a tiny fraction of its mass. This means the planets have an extraordinarily low density, more like that of Styrofoam rather than rock or water, based on new Hubble Space Telescope observations. (NASA, ESA, and L. Hustak, J.

Customs House Museum and Cultural Center to feature Belgin Yucelen’s Sculptural Garments

November 22, 2019 |

Clarksville, TN – Through January 12th, 2020, the Jostens Gallery of the Customs House Museum & Cultural Center is featuring the sculptural dresses of Belgin Yucelen.

The exhibition, titled Semblance, consists of garments portraying a past culture’s sophistication. Yucelen creates her dresses similar to the Turkish styles of the 17th through 19th centuries. She used traditional techniques and materials from Turkey and other parts of Asia to add embellishments to the metal dresses.

NASA Scientist may have discovered way to detect Life Friendly Climates on Other Worlds

May 27, 2019 |

Greenbelt, MD – NASA says scientists may have found a way to tell if alien worlds have a climate that is suitable for life by analyzing the light from these worlds for special signatures that are characteristic of a life-friendly environment.

This technique could reveal the inner edge of a star’s habitable zone, the region around a star where liquid water could exist on the surface of a rocky planet.

“Habitable planets by definition have water on their surfaces,” said Eric Wolf of the University of Colorado, Boulder. “However, water can come in the forms of ocean, ice, snow, vapor, or cloud. Each of these forms of water have very different effects on climate. ”

NASA ends Tropospheric Emission Spectrometer instrument’s mission

February 19, 2018 |

Washington, D.C. – On January 31st, NASA ended the Tropospheric Emission Spectrometer’s (TES) almost 14-year career of discovery. Launched in 2004 on NASA’s Aura spacecraft, TES was the first instrument designed to monitor ozone in the lowest layers of the atmosphere directly from space. Its high-resolution observations led to new measurements of atmospheric gases that have altered our understanding of the Earth system.

TES was planned for a five-year mission but far outlasted that term.

TES collected spectral “signatures,” illustrated here, of ozone and other gases in the lower atmosphere. (NASA)

NASA to study Earth’s Ionosphere during Total Solar Eclipse

August 14, 2017 |

Written by Lina Tran
NASA’s Goddard Space Flight Center

Greenbelt, MD – On August 21st, 2017, the Moon will slide in front of the Sun and for a brief moment, day will melt into a dusky night. Moving across the country, the Moon’s shadow will block the Sun’s light, and weather permitting, those within the path of totality will be treated to a view of the Sun’s outer atmosphere, called the corona.

But the total solar eclipse will also have imperceptible effects, such as the sudden loss of extreme ultraviolet radiation from the Sun, which generates the ionized layer of Earth’s atmosphere, called the ionosphere. This ever-changing region grows and shrinks based on solar conditions, and is the focus of several NASA-funded science teams that will use the eclipse as a ready-made experiment, courtesy of nature.

The Moon’s shadow will dramatically affect insolation — the amount of sunlight reaching the ground — during the total solar eclipse. (NASA’s Scientific Visualization Studio)

NASA’s Kepler Space Telescope finds 219 new Planet Candidates

June 20, 2017 |

Mountain View, CA –  NASA’s Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new candidates, 10 of which are near-Earth size and orbiting in their star’s habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet.

This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler’s first four years of data. It’s also the final catalog from the spacecraft’s view of the patch of sky in the Cygnus constellation.

NASA says Rosetta images show active surface on Comet 67P/Churyumov-Gerasimenko

March 24, 2017 |

Written by DC Agle
NASA’s Jet Propulsion Laboratory

Pasadena, CA – Images returned from the European Space Agency’s Rosetta mission indicate that during its most recent trip through the inner solar system, the surface of comet 67P/Churyumov-Gerasimenko was a very active place – full of growing fractures, collapsing cliffs and massive rolling boulders.

Moving material buried some features on the comet’s surface while exhuming others. A study on 67P’s changing surface was released Tuesday, March 21st, in the journal Science.

A 100 foot-wide (30 meter), 28-million-pound (12.8-million-kilogram) boulder, was found to have moved 460 feet (140 meters) on comet 67P/Churyumov-Gerasimenko in the lead up to perihelion in August 2015, when the comet’s activity was at its highest.
