Will life disappear if a black hole in the center of our galaxy erupts? Scientists have observed this in another
Astrophysicists have discovered a large-scale radiation from a supermassive black hole in the distant spiral galaxy 2MASX and are now wondering if the same thing could happen in the Milky Way.
Huge amount of helium found in the Earth’s core — scientists are forced to revise the history of the planet
Japanese and Taiwanese researchers have concluded that in the earth’s core may contain large amounts of primary helium.
Mysterious giant object distorted the solar system — it may lose one planet
Scientists say that if creating the Solar System “by the book,” it would be flatter and more round. It seems something extraordinarily large stirred it up.
Ganymede under attack: an asteroid 20 times larger than «dinosaur killer» has turned Jupiter’s moon around
The asteroid that collided with Ganymede, the largest moon of Jupiter, was 20 times larger than the one that caused the extinction of dinosaurs on Earth.
The Moon probably had many small «siblings» orbiting the Earth in the distant past
Scientists at the University of Nevada, Las Vegas, have hypothesized that in the early periods of the Earth-Moon system’s existence, it could have had small companions in polar orbits.
Much larger than we thought. New calculations show that the boundaries of the solar system need to be expanded
Until now, scientists have believed that the solar system ends in a hypothetical Oort cloud located at a distance of just over one light year from the Sun. However, a new study by American scientists may radically change this idea.
A 100-meter cave found on the Moon that could be a home for people
A group of researchers has for the first time recorded the presence of a huge cave on the Moon. With a depth of at least 100 meters, it could be an ideal place to create a permanent base for humanity on the Earth’s satellite.
From changing orbits to destroying planets: what will happen if a black hole appears in the solar system
Black holes — are not just «space vacuum cleaners», as some people think. In fact, their impact on the solar system depends on many factors. Carina Voggel, a researcher at the Strasbourg Astronomical Data Center, explains that black holes — are just highly compressed mass, not a destructive force.
Asteroid Bennu broke away from a small ocean planet — scientists analyze samples
On September 24, 2023, NASA’s OSIRIS-REx spacecraft delivered a capsule with carbon regolith to Earth, collected from the near-Earth asteroid Bennu. The samples were obtained after the probe made a seven-year journey through the solar system.
Astronomers have discovered two unknown moons of Neptune and one of Uranus — in total, the planets have 16 and 28
Thanks to ground-based telescopes, astronomers have discovered three previously unknown satellites in the space around Uranus and Neptune: one orbiting Uranus and two around Neptune. Thus, the official number of Uranus’ satellites is 28, and Neptune’s is 16.
