Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active solar plage region. This is the first time that the magnetic field in the chromosphere has been charted all the way up to its top. This finding brings us closer to understanding how energy is transferred between layers of the Sun.

February 17, 2021, Mountain View, CA The SETI Institute announces its new NASA Community College Network (NCCN). This innovative program will bring NASA subject matter experts, research findings, and educational resources into the science classrooms of the nation s community college system which, with nearly 1,200 2-year, associate degree-granting institutions represents 12 million students. NASA s Science Activation program brings the unmatched STEM resources of NASA to schools, libraries and communities across the United States., said Dr. Simon Steel, NCCN Principal Investigator. NCCN will amplify this reach into America s community colleges where many students from underserved groups start their higher education.

More than one-third of the Corn Belt in the Midwest - nearly 30 million acres - has completely lost its carbon-rich topsoil, according to University of Massachusetts Amherst research that indicates the U.S. Department of Agriculture has significantly underestimated the true magnitude of farmland erosion.
In a paper published in the
Proceedings of the National Academy of Sciences, researchers led by UMass Amherst graduate student Evan Thaler, along with professors Isaac Larsen and Qian Yu in the department of geosciences, developed a method using satellite imagery to map areas in agricultural fields in the Corn Belt of the Midwestern U.S. that have no remaining A-horizon soil. The A-horizon is the upper portion of the soil that is rich in organic matter, which is critical for plant growth because of its water and nutrient retention properties. The researchers then used high-resolution elevation data to extrapolate the satellite measurements across the Corn Belt and the tr

HANOVER, N.H. - February 12, 2021 - A newly discovered planetary system will provide researchers with the rare chance to study a group of growing planets, according to research co-led by Dartmouth.
The new system, named TOI 451, is made up of at least three neighboring planets that orbit the same sun. The planets range in size between that of Earth and Neptune.
According to the research team, NASA s Hubble Space Telescope and its planned successor, the James Webb Space Telescope, can be used to study the atmosphere of each planet. Such research could lead to information on how planetary systems like our own solar system evolve.

Astronomers may have found our galaxy s first example of an unusual kind of stellar explosion. This discovery, made with NASA s Chandra X-ray Observatory, adds to the understanding of how some stars shatter and seed the universe with elements critical for life on Earth.
This intriguing object, located near the center of the Milky Way, is a supernova remnant called Sagittarius A East, or Sgr A East for short. Based on Chandra data, astronomers previously classified the object as the remains of a massive star that exploded as a supernova, one of many kinds of exploded stars that scientists have catalogued.
