Extraterrestrial civilizations need a great deal of energy as they advance up the Kardashev scale. Fossil fuels are finite, wind and solar energy are carbon free but not as efficient as fossil fuels, and traditional nuclear ...
As physicists continue their struggle to find and explain the origin of dark matter, the approximately 80% of the matter in the universe that we can't see and so far haven't been able to detect, researchers have now proposed ...
After almost a century of speculation, proposals and searches for dark matter, physicists now know that it currently comprises about 27% of the universe's mass-energy, with an abundance over five times that of ordinary matter ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a distant star. The newfound alien world, designated TOI-4994 b, is warm and slightly smaller ...
Astronomers have employed the Hubble Space Telescope (HST) to observe an ultra-diffuse galaxy known as VCC 615. Results of the observational campaign, presented in a paper posted Dec. 2 to the preprint server arXiv, yield ...
Using the Large Millimeter Telescope (LMT) in Mexico, astronomers have performed spectroscopic observations of the Swelling Spiral galaxy. The observational campaign found that the galaxy harbors dense molecular gas in its ...
New observations from the James Webb Space Telescope suggest that a new feature in the universe—not a flaw in telescope measurements—may be behind the decade-long mystery of why the universe is expanding faster today ...

Using the MeerKAT telescope, astronomers have discovered a new odd radio circle that appears to be associated with an elliptical galaxy known as WISEA J021912.43–050501.8. The finding, which could help us better understand ...
An international team of astronomers has observed an extremely radio-loud quasar known as J1601+3102. As a result, they found that the quasar hosts a large extended radio jet. The discovery is reported in a research paper ...
