Topic: Carbon
Many of these charged particles, or ions, of oxygen, carbon, nitrogen, and argon, have been escaping Mars for billions of years as the planet has been shedding its atmosphere. Some ions, scientists predict, have been smashing into the surface of Phobos and could be preserved in its uppermost layer, according to a paper published on February 1st in the journal Nature Geoscience. ![]() An image of Phobos from March 23, 2008, taken by the High Resolution Imaging Science Experiment camera on NASA’s Mars Reconnaissance Orbiter.

NASA Astrobiologists to examine Asteroid Ryugu Dust
By the close of 2021, the Japan Aerospace Exploration Agency, or JAXA, will disperse samples of Ryugu to six teams of scientists around the globe. ![]() Artist’s concept of a NASA spacecraft speeding toward a rendezvous with an asteroid.

NASA Scientists identify Molecule in Titan’s Atmosphere that’s never been seen before
Researchers found C3H2 by using a radio telescope observatory in northern Chile known as the Atacama Large Millimeter/submillimeter Array (ALMA). ![]() These infrared images of Saturn’s moon Titan represent some of the clearest global views of the icy moon’s surface. The views were created using 13 years of data acquired by the Visual and Infrared Mapping Spectrometer instrument onboard NASA’s Cassini spacecraft.

President Donald Trump addresses United Nations General Assembly on China
“In the United States, we launched the most aggressive mobilization since the Second World War. We rapidly produced a record supply of ventilators, creating a surplus that allowed us to share them with friends and partners all around the globe. We pioneered life-saving treatments, reducing our fatality rate 85 percent since April,” said President Trump. «Read the rest of this article» Sections: Politics | No Comments
NASA’s SOFIA telescope discovers Pulsing Stars ejecting Carbon Gas, Dust into Interstellar Space
The Stratospheric Observatory for Infrared Astronomy, SOFIA, examined several types of pulsating stars in our Milky Way galaxy, watching as some spewed carbon, a key ingredient of life as we know it, into interstellar space. ![]() Image of a carbon star known as CW Leonis or IRC+10216 taken by the Herschel Space Observatory. SOFIA found that some carbon stars with especially strong pulsations, called Mira variables, distribute large amounts of carbon to interstellar space where it can be used as a building block for life and other complex structures.

NASA’s Hubble Space Telescope discovers supergiant star Betelgeuse’s Dimming is Due to Outburst
Hubble researchers suggest that the dust cloud formed when superhot plasma unleashed from an upwelling of a large convection cell on the star’s surface passed through the hot atmosphere to the colder outer layers, where it cooled and formed dust grains. The resulting dust cloud blocked light from about a quarter of the star’s surface, beginning in late 2019. By April 2020, the star returned to normal brightness. ![]() This four-panel graphic illustrates how the southern region of the rapidly evolving, bright, red supergiant star Betelgeuse may have suddenly become fainter for several months during late 2019 and early 2020. In the first two panels, as seen in ultraviolet light with the Hubble Space Telescope, a bright, hot blob of plasma is ejected from the emergence of a huge convection cell on the star’s surface. In panel three, the outflowing, expelled gas rapidly expands outward. It cools to form an enormous cloud of obscuring dust grains. The final panel reveals the huge dust cloud blocking the light (as seen from Earth) from a quarter of the star’s surface. (NASA, ESA, and E.

NASA’s Dawn Spacecraft data reveals Ceres’ Bright Areas created from Salt Water under the surface
Scientists had figured out that the bright areas were deposits made mostly of sodium carbonate – a compound of sodium, carbon, and oxygen. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Curiosity Rover discovers information in Rocks about Mars’ cold, icy past
Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren’t the type to be easily deterred. Orbiters and rovers at Mars have confirmed that the planet once had liquid water, thanks to clues that include dry riverbeds, ancient shorelines, and salty surface chemistry. ![]() Filled with briny lakes, the Quisquiro salt flat in South America’s Altiplano represents the kind of landscape that scientists think may have existed in Gale Crater on Mars.

NASA Scientists simulating Ocean Vents find evidence these features could have start Life
In a new paper in the journal Astrobiology, NASA scientists at the Jet Propulsion Laboratory describe how they mimicked possible ancient undersea environments with a complex experimental setup. They showed that under extreme pressure, fluid from these ancient seafloor cracks mixed with ocean water could have reacted with minerals from the hydrothermal vents to produce organic molecules – the building blocks that compose nearly all life on Earth. ![]() A seafloor vent called a “white smoker” spews mineral-rich water into the ocean and serves as an energy hub for living creatures. Some scientists think life on Earth may have begun around similar vents on the ocean floor billions of years ago. (NOAA/C.

Lamar Alexander reports Bipartisan Energy Legislation Gives Big Boost to Advanced Nuclear ReactorsSays legislation will help reduce carbon emissions, produce large amounts of clean, cheap, reliable energy
Last year, Alexander called for a New Manhattan Project for Clean Energy – a five year project with Ten Grand Challenges that will use American research and technology to combat climate change and put our country and the world firmly on a path toward cleaner, cheaper energy. This bill contains several provisions that would help achieve the goals of the Ten Grand Challenges. «Read the rest of this article» Sections: Politics | No Comments
