Asteroid 2002 AJ129 will make a close approach to Earth on Feb. 4, 2018 at 1:30 p.m. PST (4:30 p.m. EST / 21:30 UTC). At the time of closest approach, the asteroid will be no closer than 10 times the distance between Earth and the Moon (about 2.6 million miles, or 4.2 million kilometers).

What Dundas saw that day, and subsequently found at seven other sites, are steep cliffs, up to 100 meters tall, that expose what appears to be nearly pure ice. The discovery points to large stores of underground ice buried only a meter or two below the surface at surprisingly low martian latitudes. “This kind of ice is more widespread than previously thought,” says Dundas, who, with his co-authors, describes the cliffs this week in Science. Each cliff seems to be the naked face of a glacier, tantalizing scientists with the promise of a layer-cake record of past martian climates and space enthusiasts with a potential resource for future human bases.

We are pleased to account a Redshift Mac version called “Redshift Premium – Astronomy” which replaces the existing Mac app. It has many of the Premium features the “old” Mac version didn’t have, like telescope control and observation planner, plus a brand-new multi-window mode to display celestial events simultaneously from different perspectives. The introduction price will be 39.99 € (34,99 GBP, 35,99 USD). From January 22nd the price will be 49.99 € (43.99 GBP, 44.99 USD).

Locate a spot of land laid bare by time, and you have a direct line of sight on Mars' subterranean layers—and any ice deposited there. Now, scientists have discovered such a site. In fact, with the help of HiRISE, a powerful camera aboard NASA's Mars Reconnaissance Orbiter, they've found several.

Be sure to watch for Jupiter and Mars before dawn around January 9, 10, 11 and 12. The waning moon will close in, then sweep past them, in the sky.

Happy new year! Are you enjoying the super moon? The full Moon of 2 January 2018 occurs just 4½ hours after perigee, the closest point to Earth in the Moon’s oval-shaped orbit.

Beyond our own Milky Way Galaxy into deep space, we find a galaxy cluster called Perseus. Scientists are using NASA’s Chandra X-ray Observatory to study this cluster because it’s spewing out strong x-ray signals that might help scientists understand dark matter.

Today, scientists using data from NASA’s Kepler spacecraft announced they’d discovered an eighth planet orbiting a star 2,500 light years away. They’ve named the planet Kepler-90i after the star it orbits, Kepler-90, which is slightly hotter and more massive than our sun.

The annual Geminid meteor shower has arrived. The shower will peak overnight Dec. 13-14 with rates around one per minute under good conditions.

Heat generated by the gravitational pull of moons formed from massive collisions could extend the lifetimes of liquid water oceans beneath the surface of large icy worlds in our outer solar system, according to new NASA research. This greatly expands the number of locations where extraterrestrial life might be found, since liquid water is necessary to support known forms of life and astronomers estimate there are dozens of these worlds.

The NASA's Hubble Space Telescope peers into the distant universe to reveal a galaxy cluster called Abell 2537. Galaxy clusters such as this one contain thousands of galaxies of all ages, shapes and sizes, together totaling a mass thousands of times greater than that of the Milky Way. These groupings of galaxies are colossal — they are the largest structures in the Universe to be held together by their own gravity.

Billions of miles from Earth, at the edge of interstellar space, a long-dormant part of a far-flung spacecraft came to life this week.

This weekend Earth will have front row seats for the first and last supermoon of 2017 in the next few days, known as the ‘full cold moon’. Appearing 14% larger and 30% brighter than the moon usually does, according to NASA, it will be well worth looking out for.

Jovian clouds in striking shades of blue in this new view taken by NASA’s Juno spacecraft. The Juno spacecraft captured this image when the spacecraft was only 11,747 miles (18,906 kilometers) from the tops of Jupiter’s clouds — that’s roughly as far as the distance between New York City and Perth, Australia. The color-enhanced image, which captures a cloud system in Jupiter’s northern hemisphere, was taken on Oct. 24, 2017 at 10:24 a.m. PDT (1:24 p.m. EDT) when Juno was at a latitude of 57.57 degrees (nearly three-fifths of the way from Jupiter’s equator to its north pole) and performing its ninth close flyby of the gas giant planet.

Astronauts have done over 200 spacewalks outside of the International Space Station, and the latest one offers some pretty stunning views of our planet. NASA astronaut Randy Bresnik posted a video he took with a GoPro camera on his latest spacewalk, which occurred last month. In the video, after latching himself safely to the outside of the space station, he takes a moment to look at the Earth. The round ball is dotted with clouds floating over oceans and land, suspended over pure darkness. It’s a mesmerizing view and reminder of “the beauty of our planet Earth,” as Bresnik says.

Astronomers have discovered some of the oldest stars in our Milky Way galaxy by determining their locations and velocities, according to a study led by scientists at Georgia State University.

An asteroid that visited us from interstellar space is one of the most elongated cosmic objects known to science, a study has shown. Discovered on 19 October, the object's speed and trajectory strongly suggested it originated in a planetary system around another star. Astronomers have been scrambling to observe the unique space rock, known as 'Oumuamua, before it fades from view. Their results so far suggest it is at least 10 times longer than it is wide.
