The Milky Way may be swarming with planets with oceans and continents like here on Earth

According to a new study, Earth, Venus and Mars were created from small dust particles containing ice and carbon. The discovery opens up the possibility that the Milky Way may be filled with aquatic planets.

Big galaxies steal star-forming gas from their smaller neighbors

Large galaxies are known to strip the gas that occupies the space between the stars of smaller satellite galaxies. Astronomers have discovered that these small satellite galaxies also contain less 'molecular' gas at their centres.

Astrophysicists propose that all high-energy cosmic neutrinos are born by quasars

Scientists studied the arrival directions of astrophysical neutrinos with energies more than a trillion electronvolts (TeV) and came to an unexpected conclusion: all of them are born near black holes in the centers of distant active galaxies powerful radio sources. Previously, only neutrinos with the highest energies were assumed to be obtained in sources of this class.

Has Earth been visited by an alien spaceship? Harvard professor Avi Loeb vs everybody else

Avi Loeb, a Harvard professor of astronomy, suggested in a recent book that asteroid Oumuamua is indeed an alien spaceship. But how feasible is this? And how come most scientists disagree with the claim?

New metamaterials for studying the oldest light in the universe

To capture the ancient, cold light from the cosmic microwave background, researchers use specialized telescopes equipped with ultrasensitive cameras for detecting millimeter-wavelength signals. The next-generation cameras will contain up to 100,000 superconducting detectors.Scientists have developed a new type of metamaterials-based antireflection coating for the silicon lenses used in these cameras.

The smallest galaxies in our universe bring more about dark matter to light

A team of researchers has investigated the strength of dark matter scattered across the smallest galaxies in the universe using stellar kinematics. They discovered that the strength of dark matter is quite small, suggesting that dark matter does not easily scatter together.

Mars: Perseverance rover set for nail-biting landing - here's the rocket science

Following 'seven minutes of terror' after it reaches Mars' upper atmosphere, NASA's Perseverance rover is expected to land on the surface of the red planet at 20:55 GMT on February 18. This is incredibly hard to do, with only about 40% of missions succeeding.

Astronomers confirm orbit of most distant object ever observed in our solar system

Astronomers have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object observed in our solar system. The planetoid, which has been nicknamed 'Farfarout', was first detected in 2018, and the team has now collected enough observations to pin down its orbit.

Study of supergiant star Betelgeuse unveils the cause of its pulsations

Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020, which has prompted speculation that Betelgeuse may be about to explode.
