Comet 45P Passes Near the Earth 

A large snowball has just passed the Earth. Known as Comet 45P/Honda–Mrkos–Pajdušáková", or 45P for short, the comet came 10 times closer to Earth yesterday than the Earth ever gets to the Sun. During this passage, the comet was photographed sporting a thin ion tail and a faint but expansive green coma. The green color is caused mostly by energized molecules of carbon. Comet 45P became just bright enough to see with the unaided eye when it came closest to the Sun in December. Now, however, the comet is fading as it heads back out to near the orbit of Jupiter, where it spends most of its time. The kilometer-sized nucleus of ice and dirt will return to the inner Solar System in 2022.

According to NASA, a neighboring star has 7 Earth-like planets in its orbit

  • Seven Earth-like planets have been found orbiting a sun not too far — in space terms, at least — from our own.
  • NASA announced Wednesday that the planets resemble Earth in composition and spacing from their star, which means their conditions might be favorable to liquid water and life, Time reported.
  • “The planets form a very compact system,” Michaël Gillon of Belgium’s University of Liège, said in a teleconference, according to Time. “They are very close to their star and are reminiscent of the system of moons that orbit Jupiter. They could have liquid water and life.”
  • Astronomers studied the star, Trappist-1 — which, at 39 light years away from Earth, is considered a relative neighbor — for six years, using telescopes located all over the world, plus the Spitzer Space Telescope. Read more (2/22/17 2:04 PM)

A small, faint star relatively close by is home to seven Earth-size planets with conditions that could be right for liquid water and maybe even life.

The discovery sets a record for both the most Earth-size planets and the most potentially habitable planets ever discovered around a single star.

The strange planetary system is quite compact, with all of these worlds orbiting their star closer than Mercury orbits the sun, according to a newly published report in Nature.

“If you were on the surface of one of these planets, you would see the other ones as we see the moon, or a bit smaller,” says Michaël Gillon, an astronomer at the University of Liège in Belgium. “The view would be very impressive.”

A full moon, lunar eclipse and comet may all be visible on Friday

  • A full moon, lunar eclipse and a comet may all be visible to much of the world Friday night if the skies are clear.
  • Early in the night, the snow moon will pass into the Earth’s penumbra, shading part of it.
  • A few hours later, the bright green comet 45P will shoot past the Earth.
  • Though penumbral eclipses are typically not as noticeable as total lunar eclipses, the moon is expected to pass so deeply into the Earth’s shadow that it will appear far darker than usual.
  • The green comet, which visits our neck of the solar system every five years, will whiz within 7.7 million miles of Earth at a speedy clip of about 14.2 miles per second.
  • Most of the world — except for Australia, New Zealand, parts of East Asia and Hawaii — will be able to see the eclipse. Read more (2/9/17 3:30 PM)
