Hubble Space Telescope captures a new active asteroid named 6478 Gault. The asteroid ejected matter into space (between October and December 2018), leaving behind two long tails. The debris from the long tail was captured earlier in December 2018...
A new theory says that Big Bang was a starting point of an anti-universe, a mirror image of the present universe. In anti-universe, time flows in the opposite direction and antimatter dominates. The Big Bang cosmology describes the history and...
The new point-circle method accurately calculates the distance (averaged over time) between two planets. It shows that Mercury is the nearest neighbor to all 7 other planets in the solar system, including Earth. In school, you have been taught...
Astronomers discovered 83 previously unknown quasars powered by supermassive black holes. These quasars are approximately 13 billion light-years away from Earth. The observations revealed that in every cubic giga-light-year there exists a...
Researchers observed more than 20-year-old data and found that Earth’s atmosphere extends up to 630,000 kilometers away. However, astronomers would still call it a vacuum because it contains very less amount of hydrogen atoms. Earth’s...
In the last 20 years or so, it seems like a new exoplanet has been discovered almost on a daily basis. The term exoplanet is used to classify those planets which have extrasolar (outside our solar system) origins. Although the first-ever confirmed...
Researchers create a precise 3D map of the Milky Way out to its far outer zones. The new map shows that the S-shaped disc of stars becomes progressively warped and twisted the further away the stars are from the center of the Milky Way. We...
The magnetic field of our Sun behaves quite differently than presently believed. The sound waves originating from the Sun’s internal acoustic oscillations affect the magnetic waves at its surface. These waves make the entire corona vibrate...
Researchers use quasars to measure the universe’s expansion across the past 12 billion years. They examined the XMM-Newton archive and gathered X-ray data of more than 7,000 quasars. Our Universe is thought to consist of 3 kinds of substance:...
Physicists build a new model that suggests our universe may be sitting on a bubble expanded by dark energy. All particles in our universe are the endpoints of strings (as per string theory) extending out into another dimension. In 1925, an...
Researchers use Saturn’s rings to study the planet’s seismology. As per calculations, the length of one day on Saturn is 10 hours 33 minutes and 38 seconds. Measuring the rotation of Saturn is not as easy as it sounds. That’s...
Like almost anything in the universe, stars born, live their life and then die. They are also one of the most diverse things we know today. The most commonly used criteria of classifying stars is based on their spectral characteristics, in which...
