Most distant cosmic jet providing clues about early universe

Astronomers using the VLA and VLBA have found the most distant cosmic jet yet discovered, material propelled at nearly the speed of light by a supermassive black hole in the core of a galaxy some 13 billion light-years from Earth.

Establishing the origin of solar-mass black holes and the connection to dark matter

What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter? Dark matter comprises the majority of matter in the Universe, but its nature remains unknown.

New study suggests supermassive black holes could form from dark matter

Scientists propose that rather than the conventional formation scenarios involving 'normal' matter, supermassive black holes could instead form directly from dark matter in high density regions in the centres of galaxies.

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.
