Stars are born in an enormous cloud of interstellar dust and hydrogen gas called a nebula. Nebulae represent the building blocks for stars,galaxies,and planets in the universe. Emission nebulae are hot,discrete clouds of primarily ionized hydrogen that glow with their own light. Reflection nebulae emit a bluish glow by reflecting the scattered light of nearby…

Comets
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the…
🌞 Today’s Motivation ⏲️
“The idea that Area 51 was this test facility working to move science and technology faster and further than any other nation is true and is one of the great hallmarks of Area 51. There are other areas of the base that are controversial – but they both exist simultaneously – out there in the…
Using the Universe’s Coldest Material in a New Search for Dark Matter
Scientists have been able to observe the universe and determine that about 80% of the its mass appears to be “dark matter,” which exerts a gravitational pull but does not interact with light, and thus can’t be seen with telescopes. Our current understanding of cosmology and nuclear physics suggests that dark matter could be made…
Future Gravitational Wave Detectors to Detect Millions of Black Holes & the Evolution of the Universe
Gravitational-wave astronomy provides a unique new way to study the expansion history of the Universe. On August 17, 2017, the LIGO and Virgo collaborations first detected gravitational waves from a pair of neutron stairs merging. The gravitational wave signal was accompanied by a range of counterparts identified with electromagnetic telescopes. This multi-messenger discovery allowed astronomers to directly measure the…
New Model to Track COVID-19’s Spread – Very Accurately
Yale University researchers and colleagues in Hong Kong and China have developed an approach for rapidly tracking population flows that could help policymakers worldwide more effectively assess risk of disease spread and allocate limited resources as they combat the COVID-19 pandemic. The approach, described in a study published early online on April 29 in the journal Nature, differs from…
