NASA picks Four Small Mission Concepts to Study the Universe
“The principal investigators of these concept studies bring innovative, out-of-the-box thinking to the problem of how to do high-impact astrophysics experiments on a small budget,” said Thomas H. Zurbuchen, associate administrator of NASA’s Science Mission Directorate. “Each of the proposed experiments would do something no other NASA telescope or mission can do, filling important gaps in our understanding of the universe as a whole.” ![]() As neutron stars collide, some of the debris blasts away in particle jets moving at nearly the speed of light, producing a brief burst of gamma rays.

NASA finishes final tests on James Webb Space Telescope Sunshield
“This is one of Webb’s biggest accomplishments in 2020,” said Alphonso Stewart, Webb deployment systems lead for NASA’s Goddard Space Flight Center in Greenbelt, Maryland. ![]() NASA’s James Webb Space Telescope’s final tests are underway with the successful completion of its last sunshield deployment test, which occurred at Northrop Grumman in Redondo Beach, California.

NASA reports ‘Great’ Conjunction of Jupiter, Saturn happens night of December 21st
In 1610, Italian astronomer Galileo Galilei pointed his telescope to the night sky, discovering the four moons of Jupiter – Io, Europa, Ganymede, and Callisto. In that same year, Galileo also discovered a strange oval surrounding Saturn, which later observations determined to be its rings. ![]() Saturn, top, and Jupiter, below, are seen after sunset from Shenandoah National Park, Sunday, Dec. 13, 2020, in Luray, Virginia. The two planets are drawing closer to each other in the sky as they head towards a “great conjunction” on December 21, where the two giant planets will appear a tenth of a degree apart.

NASA’s Hubble Space Telescope finds Exoplanet with Extreme Orbit
This is the first time that astronomers have been able to measure the motion of a massive Jupiter-like planet that is orbiting very far away from its host stars and visible debris disk. This disk is similar to our Kuiper Belt of small, icy bodies beyond Neptune. ![]() This Hubble Space Telescope image shows the environment around double star HD 106906. The brilliant light from these stars is masked here to allow fainter features in the system to be seen. (Credits: NASA, ESA, M. Nguyen (University of California, Berkeley), R.

NASA’s Lunar Gateway to be equipped with Instruments to Forecast Weather Forecast for Artemis Missions
For Artemis astronauts traveling on missions to the Moon, two space weather instrument suites, NASA’s HERMES and ESA’s ERSA, will provide an early forecast. Weather in this case means energized, subatomic particles and electromagnetic fields hurtling through the solar system. ![]() Artist’s concept of the Gateway Power and Propulsion Element, or PPE, and Habitation and Logistics Outpost, or HALO, in orbit around the Moon. The gold box on the right side of the image depicts the HERMES payload. The ERSA payload is the silver box just below it. (NASA) «Read the rest of this article» Sections: Technology | No Comments
NASA Kepler Space Telescope data reveals around Half of Sun Like Stars could have Rocky, Potentially Habitable Planets
According to new research using data from NASA’s retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our Sun could have a rocky planet capable of supporting liquid water on its surface. ![]() This illustration depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone.

NASA’s New Horizons spacecraft measurements reveals loads of Hydrogen in Interstellar Medium
In this stellar no-man’s land, particles and light shed by our galaxy’s 100 billion stars jostle with ancient remnants of the big bang. This mixture, the stuff between the stars, is known as the interstellar medium. Its contents record our solar system’s distant past and may foretell hints of its future. «Read the rest of this article» Sections: Technology | No Comments
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.

NASA says Massive Stars Are Factories for Ingredients to Life
It found massive quantities of water and organic molecules in these swirling, disk-shaped clouds, offering new insights into how some of the key ingredients of life get incorporated into planets during the earliest stages of formation. ![]() Illustration of a dusty disc rotating around a massive newborn star that’s about 40 times the size of the Sun. SOFIA, the Stratospheric Observatory for Infrared Astronomy, found the inner regions of two of these kinds of discs are filled with organic molecules that are important for life as we know it. These include water, ammonia, methane, and acetylene — which is a chemical building block to larger and more complex organic molecules — illustrated in the call out.
