Comet 252P/LINEAR will safely fly past Earth on March 21, 2016, at a range of about 3.3 million miles (5.2 million kilometers). The following day, comet P/2016 BA14 will safely fly by our planet at a distance of about 2.2 million miles (3.5 million kilometers). Credits: NASA/JPL-Caltech

Two comets that will safely fly past Earth later this month may have more in common than their intriguingly similar orbits. They may be twins of a sort. Comet P/2016 BA14 was discovered on Jan. 22, 2016, by the University of Hawaii’s PanSTARRS telescope on Haleakala, on the island of Maui...

Artist’s illustration of turbulent winds of gas swirling around a black hole. Some of the gas is spiraling inward, but some is being blown away.

New research led by astrophysicists at York University has revealed the fastest winds ever seen at UV wavelengths near a supermassive black hole. “We’re talking wind speeds of 20% the speed of light, which is more than 200 million kilometres an hour. That’s equivalent to a category 77 hurricane,” says Jesse Rogerson, York U. “And we have reason to believe that there are quasar winds that are even faster.”

Astronomers have known about the existence of quasar winds since the late 1960s. At least 1 in 4 quasars have them...

3 years ago a team of Russian scientists working with the global MASTER network of robotic telescopes spotted that the giant star in Leo minor with a catalogue number TYC 2505-672-1, which was considered to be extinct, in fact just faded – its brightness decreased nearly 100 times.

The MASTER network of telescopes was constructed by MSU scientists for a purpose of detecting and researching Gamma-ray bursts and also thermonuclear flashes on white dwarfs, galactic center flares and quasars...

Extrasolar planet swings around its star like it’s a comet. Led by SF State Uni astronomer Stephen Kane, a team has spotted an extrasolar planet about 117 light-years from earth that boasts the most eccentric orbit yet seen. They detected a signal of reflected light from the planet HD 20782 – a “flash” of starlight bouncing off the eccentric planet’s atmosphere as it made its closest orbital approach to its star.

In this case, “eccentric” refers to how elliptical a planet’s orbit is around its star...
