As we celebrate the #SpaceStation20th anniversary, NASA astronaut Don Pettit explains how his perception of the Earth changed during his time aboard the space station.

Go NASA’s Hubble Space Telescope. It’s your birthday. ✨

This Friday marks 30 years of stunning imagery and ground breaking discoveries for the one-of-a-kind orbiting telescope. Join us in observing #Hubble30 by sharing your favorite galactic image! https://go.nasa.gov/3aoSMxH

It took centuries, but we now know the size of the Universe, this will blow your mind! 😱

While 2020 continues to be a difficult year, there is a little good news to look forward to tonight (June 5): a near-Earth asteroid will whiz safely by our planet, and astronomers may be able to see the monster rock’s flight through telescopes.

The asteroid, known as 2002 NN4, is approaching Earth – but fortunately, not too closely. The space rock will fly by at the equivalent of 13.25 times the distance between Earth and the moon, which is roughly 3.2 million miles (5.2 million kilometers) from our planet. The asteroid’s closest approach to us will be at 11:20 p.m. EDT (0320 GMT June 6).

The mole instrument on NASA’s Mars InSight lander has made some progress burrowing into the Red Planet.

Strange, powerful signals from deep space called fast radio bursts are slippery little suckers.

Most of them just flash once, a mysterious huge spike in the radio data out of nowhere, lasting just milliseconds at most. They can’t be predicted, and because they’re so brief, they’re incredibly hard to trace.

Hard; but not impossible. Less than a year ago, for the first time, astronomers announced they traced one of these mysterious one-off signals to its source galaxy. Since then, their techniques have allowed them to trace three more.

Mars — glorious, dusty, complex Mars — may once have been even more dazzling. New research provides even more evidence that a rubbly ring once circled the Red Planet.

The new clue lies in Deimos, the smaller of the two Martian moons. It’s orbiting Mars at a slight tilt with respect to the planet’s equator — and this could very well be the result of the gravitational shenanigans caused by a planetary ring.

Ring systems aren’t actually all that uncommon. When you think about ring systems, your mind immediately leaps to Saturn, no doubt — but half the planets in the Solar System have rings, Saturn, Uranus, Neptune, and Jupiter. Dwarf planet Haumea, and centaurs Chiron and Chariklo also have rings.

NASA is monitoring an asteroid that may be as large as the Empire State Building, expected to pass Earth on Saturday, June 6.

Asteroid 2002 NN4 is estimated to be 250–570 meters (820–1,870 feet) in diameter, according to NASA’s Jet Propulsion Laboratory (JPL). New York City’s iconic Empire State Building is more than 1,400 feet tall at its tip.

The asteroid may seem daunting, but it will pass Earth at a safe distance, a representative for JPL told CBS News.
