Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks here are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars.

NASA confirms evidence that liquid water flows on today’s Mars These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona).

What is a Supermoon Lunar Eclipse?

We’ve told you that on Sept. 27 a supermoon lunar eclipse will occur in the U.S. And much of the world, but what does that mean?

One important note, is that this event can be referred to in many different ways: 

Supermoon Lunar Eclipse

Super Blood Moon

Harvest Moon Eclipse

Supermoon Eclipse

All slightly different names, but apply to the same spectacular event that will occur this weekend. 

Since it’s rare that both a supermoon and an lunar eclipse occur at the same time, let’s break it down. 

1) Supermoon

A supermoon is a full or new moon that falls closest to the fall equinox, and is at its closest approach to the Earth. This results in the moon appearing up to 14% larger in diameter.

2) Lunar Eclipse 

A lunar eclipse occurs when the moon passes directly behind the Earth into its shadow. This can give the moon a red tint.

3) A Supermoon Lunar Eclipse!

The combination of these two events does not happen very often. In fact, since 1900 a supermoon lunar eclipse has only happened 5 times! The last time this occurred was 1982, and if you miss the event this year, your next opportunity won’t come until 2033.

This year, the event will be visible from the Americas, Europe and Africa on the night of Sept. 27. Here’s a full schedule of the supermoon eclipse:

If it’s cloudy in your area on Sept. 27, don’t worry! NASA Television will be providing a live stream of the event, so you can tune in and enjoy the show.

On September 27th, 2015 there will be a very rare event in the night sky – a supermoon lunar eclipse. Watch this animated feature to learn more.

The latest images (as of Sept. 11, 2015) downloaded from NASA's New Horizons spacecraft were stitched together and rendered on a sphere to make this flyover. This animation, made with the LORRI (Long Range Reconnaissance Imager) images, begins with a low-altitude look at the informally named Norgay Montes, flies northward over the boundary between informally named Sputnik Planum and Cthulhu Regio, turns, and drifts slowly east. During the animation, the altitude of the observer rises until it is about 10 times higher to show about 80% of the hemisphere New Horizons flew closest to on July 14, 2015.

This colorful bubble is a planetary nebula called NGC 6818, also known as the Little Gem Nebula. The rich glow of the cloud is just over half a light-year across — humongous compared to its tiny central star — but still a little gem on a cosmic scale. © ESA/Hubble & NASA, Acknowledgement: Judy Schmidt

The Mercury Atmosphere and Surface Composition Spectrometer (MASCS) instrument aboard NASA's MESSENGER spacecraft was designed to study both the exosphere and surface of the planet Mercury. To learn more about the minerals and surface processes on Mercury, the Visual and Infrared Spectrometer (VIRS) portion of MASCS has been diligently collecting single tracks of spectral surface measurements since MESSENGER entered Mercury orbit on March 17, 2011. The track coverage is now extensive enough that the spectral properties of both broad terrains and small, distinct features such as pyroclastic vents and fresh craters can be studied. To accentuate the geological context of the spectral measurements, the MASCS data have been overlain on the monochrome mosiac from the Mercury Dual Imaging System (MDIS), an instrument with wide- and narrow-angle cameras to map the rugged landforms and spectral variations on Mercury’s surface. © NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington
