Earth's 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (@NOAA). Scientists at our Goddard Institute for Space Studies (GISS) analyzed measurements from 6,300 locations and found that Earth's average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late-19th century, largely a result of human emissions into the atmosphere. This makes 2016 the third year in a row to set a new record for global average surface temperatures.

Magnetic arcs of plasma that spiraled above two active regions held their shape fairly well over 18 hours (Jan. 11-12). The charged plasma is being controlled the magnetic field lines of the active regions. The field lines become clearly visible when viewed in this wavelength of extreme ultraviolet light. Often the arches bend and twist more dynamically than the relatively stable ones seen here.

We are saddened by the loss of retired NASA astronaut Gene Cernan, the last man to walk on the moon. Cernan, commander of Apollo 17, died today, Jan. 16. "We leave as we came, and, God willing, we shall return, with peace and hope for all mankind." -- Cernan's closing words on leaving the moon at the end of Apollo 17 Credit: NASA #nasa #apollo #apollo17 #space #moon

Here's a view you don't normally see on the other end of feet! 'This is what a spacewalk is: 400km of void under your feet,' wrote European Space Agency astronaut Thomas Pesquet (@thom_astro). Two astronauts spent Friday morning working outside the International Space Station (@ISS) in the vacuum of space!

Crescent Jupiter with the Great Red Spot: This image of a crescent Jupiter and the iconic Great Red Spot was created by a citizen scientist (Roman Tkachenko) using data from Juno's JunoCam instrument. You can also see a series of storms shaped like white ovals, known informally as the 'string of pearls.' Below the Great Red Spot a reddish long-lived storm known as Oval BA is visible. The image was taken on Dec. 11, 2016, as the Juno spacecraft performed its third close flyby of Jupiter. At the time the image was taken, the spacecraft was about 285,100 miles (458,800 kilometers) from the planet.

The beautiful spiral galaxy visible in the center of the image is in the Virgo constellation and imaged by the Hubble Space Telescope. It presents an interesting puzzle. At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way, but first appearances can be deceptive! The Milky Way galaxy, like most large galaxies, has a supermassive black hole at its center, but some galaxies are centered on lighter, intermediate-mass black holes. This is such a galaxy - in fact, it is centered on one of the lowest black hole masses known in any luminous galactic core. What puzzles scientists about this particular galaxy is that the calculations don't add up. With such a relatively low mass for the central black hole, models for the emission from the object cannot explain the observed spectrum. There must be other mechanisms at play in the interactions between the inner and outer parts of the accretion disk surrounding the black hole.

Second spacewalk of 2017 successfully complete! Station (@ISS) Commander Shane Kimbrough (@astro_kimbrough) and @europeanspaceagency astronaut Thomas Pesquet (@thom_astro) concluded their spacewalk at 12:20 p.m. EST today. During the nearly six hour spacewalk, the two astronauts successfully installed three new adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries on the International Space Station. This image was posted by Shane, who wrote, 'Went outside for a #spacewalk today with @Thom_astro. So amazing to be a part of a huge TEAM that made it all happen.'

That's no moon... oh wait, yes it is. It's Saturn's moon Mimas and it's large Herschel Crater. Shadows cast across the moon, provide an indication of the size of the crater's towering walls and central peak. Named after the icy moon's discoverer, astronomer William Herschel, the crater stretches 86 miles (139 kilometers) wide -- almost one-third of the diameter of Mimas (246 miles or 396 kilometers) itself. Large impact craters often have peaks in their center. Herschel's peak stands nearly as tall as Mount Everest on Earth.

This elongated coronal hole rotated across the surface of the sun this past week so that it is now streaming solar wind towards Earth. Coronal holes are areas of open magnetic field from which solar wind particles stream into space. The particle stream will likely generate aurora here on Earth. In this wavelength of extreme ultraviolet light, the coronal hole appears as a dark area near the center and lower portion of the sun.

Like monsters hiding under your bed... monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes. But they give themselves away when material they feed on emits high-energy X-rays that our NuSTAR mission can detect. That's how NuSTAR recently identified two gas-enshrouded supermassive black holes, located at the centers of nearby galaxies. NGC 1448, a galaxy with an active galactic nucleus hidden by gas and dust, is seen in this image.

Your Home Planet, as Seen From Mars! From the most powerful telescope orbiting Mars comes a new view of Earth and its moon, showing continent-size detail on the planet and the relative size of the moon. The image combines two separate exposures taken on Nov. 20, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. The images were taken to calibrate HiRISE data, since the reflectance of the moon's Earth-facing side is well known. For presentation, the exposures were processed separately to optimize detail visible on both Earth and the moon. The moon is much darker than Earth and would barely be visible if shown at the same brightness scale as Earth.
