This is a galaxy that's been catalogued as NGC 1052-DF2. Astronomers call it the "see-through" galaxy since you can see right through it and observe other and more distant galaxies behind it. Researchers have found that the galaxy is missing most, if not all, of its dark matter. (NASA, ESA, and P. van Dokkum (Yale University))

Scientists say that the invisible and mysterious dark matter makes up about 27% of all material in the universe. Regular or normal matter that you see and touch every day takes up 5% and the remaining 68% comes from an enigmatic form of energy called dark energy. According to NASA, dark matter serves as a type of […]

A Blast of Gamma Rays from Halfway Across the Universe Detected

December 16, 2015

Back in April 2015, a surge of high-powered gamma rays from half-way across the universe crashed into Earth’s atmosphere. But, according to the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the burst of gamma rays didn’t put any of us in danger and produced no noticeable effects since the high-energy rays are blocked by Earth’s atmosphere. Astronomers, using […]

Ground-Based Telescope Observes Exoplanet Transiting Bright Star

December 1, 2014

For the first time, an international team of astronomers has used a ground-based telescope to detect and observe the transit of a planet in front of a Sun-like star outside of our own solar system. Until now, only space-based telescopes were capable of detecting the transits of exoplanets as they passed by bright stars. Distortions […]
