Grab Your Telescope: Jupiter Will Shine Its Brightest Tonight

  Grab Your Telescope: Jupiter Will Shine Its Brightest Tonight This weekend I got to experience the dark skies over a nameless lake somewhere between Grand Forks, North Dakota and Bemidji, Minnesota. It was my first time seeing the faint band of our own Milky Way. But we had our telescope pointed on something we could have seen just as easily from a Brooklyn stoop: Jupiter, the largest planet in the solar system. Jupiter is in opposition today, meaning it’s exactly opposite the sun in the sky, like the Moon when it’s full. The gas giant will be brighter than any star in the sky. I was able to see the bands of gas and dust and the four brightest moons, Ganymede, Callisto, Europa, and Io, with a small telescope.

A new photo shows the Earth and moon as seen from deep space by a NASA probe near the sun. The picture was captured by the Messenger spacecraft May 6 while it was making its way toward Mercury. So far, Messenger has been studying Mercury from afar .

In 1990, NASA’s Voyager 1 space probe was instructed to take one final image of Earth before it left the Solar System and entered interstellar space, at the request of renowned astronomer and author Carl Sagan.

In the picture, which was taken from a record distance of about 3.7 billion miles, Earth appears to be smaller than a single pixel—a “pale blue dot” set against the vastness of space, as Sagan described it in a speech at Cornell University.

Now, a tiny spacecraft known as MarCO-B has just taken its own version of the “pale blue dot” image from an admittedly smaller distance of more than 620,000 miles, in which both the Earth and the Moon are visible as tiny specks.

MarCO-B, affectionately known as “Wall-E” to its operators, used a fisheye camera to take the photo on May 9, as part of a process to confirm that the spacecraft’s high-gain antenna had properly unfolded. As a bonus, the team captured the Earth and the Moon in the shot.

"Consider it our homage to Voyager," said Andy Klesh from NASA's Jet Propulsion Laboratory, in Pasadena, California.

MarCO-B is a CubeSat—a class of small, cube-shaped spacecraft that were originally designed to teach university students about satellites. They are now a major commercial technology, providing data on everything from environmental changes to shipping routes.

MarCO-B and its twin, MarCO-A, are the first CubeSats ever launched into deep space—most never go beyond Earth’s orbit. They are currently traveling towards Mars in support of NASA’s InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) robotic lander, which will attempt to touch down on the Red Planet on November 26.

The MarCOs will beam back data to Earth using their high-gain antennas—should they complete their journey—as InSight enters the thin Martian atmosphere. Findings from the mission could help expand the use of CubeSats in the future, according to NASA scientists.

China launches satellite to explore dark side of moon: Xinhua .
China launched a relay satellite early on Monday designed to establish a communication link between earth and a planned lunar probe that will explore the dark side of the moon, the official Xinhua news agency said. Citing the China National Space Administration, Xinhua said the satellite was launched at 5:28 a.m. (2128 GMT Sunday) on a Long March-4C rocket from the Xichang launch center in the southwest of the country.
