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. ![]() Standing in for a rover, a field team sets up equipment in a dry lakebed in the Nevada desert in February 2020. As part of the exercise, scientists spread around the world sent commands for images and data, as they will once Perseverance lands on Mars in February 2021.

NASA’s Hubble Space Telescope observations gives clues to makeup of Super Puffy Planets
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. Olmsted, D. Player and F. Summers (STScI)) «Read the rest of this article» Sections: Technology | No Comments

Customs House Museum and Cultural Center to feature Belgin Yucelen’s Sculptural Garments
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. «Read the rest of this article» Sections: Events | No Comments

NASA Scientist may have discovered way to detect Life Friendly Climates on Other Worlds
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. ” ![]() Artist rendering of a red dwarf or M star, with three exoplanets orbiting. About 75 percent of all stars in the sky are the cooler, smaller red dwarfs. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA ends Tropospheric Emission Spectrometer instrument’s missionWritten by Carol Rasmussen
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) «Read the rest of this article» Sections: Technology | No Comments
NASA to study Earth’s Ionosphere during Total Solar EclipseWritten by Lina Tran
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 Kepler Space Telescope finds 219 new Planet CandidatesWritten by Michele Johnson
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’s Kepler space telescope team has identified 219 new planet candidates, 10 of which are near-Earth size and in the habitable zone of their star.

NASA says Rosetta images show active surface on Comet 67P/Churyumov-GerasimenkoWritten by DC Agle
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.
