So you missed Mercury transiting the Sun last month and thought you were going to have to wait another three whole years to see the rare astronomical event?

Each of the videos released by NASA s Scientific Visualization Studio this week depicts the same transit event—Mercury crossing the Sun on May 9th, 2016—by combining partial images taken at 12 second intervals with full disk images captured every 90 seconds.

With three different filters, NASA is offering us a range of 4K-by-4K viewing experiences that show three distinct faces of our mighty Sun: fiery, smoldering, and glowering.

This is the probably the best Mercury transit you re going to see without pulling up close on a spacecraft, and frankly, better in the sense that you don t burn your face off watching.

As a small aside, it s a bit disturbing NASA waited until now to release these incredibly high definition, carefully edited photos and videos.

As Fox News made clear this week, Murica expects a little better.

NASA s consistently surprising Cassini orbiter is rapidly approaching the end of its life, but before it signs off forever it s been taking some really fantastic shots of Saturn as it swings and dives between the planet s rings.

The latest snapshots sent back by Cassini aren t just extremely cool looking, they re also one of the most detailed glimpses of Saturn s iconic rings ever shot.

Just type in a Name and select a State.

Then brace yourself for what you might find on you or anyone else!

Saturn s A and B rings are both captured in impressive detail in the photos, and you can even make out relatively small touches that aren t typically visible.

The small white vertical gashes in the photo of the A ring below are what NASA calls propellers, due to their shape.

NASA s MErcury Surface, Space ENvironment, GEochemistry, and Ranging MESSENGER craft has found evidence that Sol's innermost planet is tectonically active.

That's kind of a big deal because until now only Earth was known to be tectonically active.

And because tectonic activity brings lovely stuff up from a planet's innards, and that lovely stuff is very useful for cooking chemicals that have the potential to eventually form cells, knowing that there's at least one other tectonically active world out there is encouraging.

MESSENGER found evidence of tectonic activity after lowering its altitude to snap more detailed pictures of Mercury.

Doing so revealed what NASA is calling previously undetected small fault scarps— cliff-like landforms that resemble stair steps.

Fault scarps can appear after events like earthquakes, which can themselves be caused by a planet cooling and contracting.

Astronomers just discovered a valley on Mercury that dwarfs the Grand Canyon.

At about 250 miles wide and 600 miles long, Mercury s great valley would stretch between New York City, Washington D.C. and Detroit and cut into the Earth twice as deep as does the Grand Canyon.

The scale of this valley is enormous, University of Maryland assistant professor Laurent Montesi told Digital Trends.

We do not have anything comparable on Earth.

Earth s large valleys form when rivers cut through rock and the planet s crust stretches open.

Mercury s is the result of a single crust shrinking and creasing like a crumbled napkin.

The Hubble Space Telescope has spied a dark vortex on the planet Neptune, a spot in the ice giant s atmosphere the size of the continental United States.

Dark spots on the planet are high-pressure systems which usually are found hand-in-hand with bright clouds, NASA says.

Indeed, astronomers saw such bright clouds in 2015, and the Hubble itself saw a dark spot near them that same year.

Then, in May 2016, Hubble saw the dark vortex again, confirming its previous observation.

"And the companion clouds are similar to so-called orographic clouds that appear as pancake-shaped features lingering over mountains on Earth."

Neptune is so far away from the sun about 2.8 billion miles that it takes an incredibly long time for one year on it to pass— the blue, ringed planet takes nearly 165 Earth years to make one trip around the sun.

In the next five billion years, the sun will expand to one hundred times its current size, engulfing Mercury and Venus, and obliterating all life on Earth.

That s according to new analysis of the star L2 Puppis, which five billion years ago was very similar to our own.

The star, just 200 light years away, sheds light on how the sun will evolve and the fate of the rest of the solar system.

Five billion years from now, the sun will have grown into a red giant star, more than a hundred times larger than its current size, said Professor Leen Decin from the KU Leuven Institute of Astronomy.

It will also experience an intense mass loss through a very strong stellar wind.

talked about the Earth-like planet called Proxima B

Back in August we first .

The cool bit about this planet is that it is relatively close to the Earth and is believed to be potentially life supporting.

Proxima B lies 4.25 light-years from the Earth and is orbiting the star Proxima Centauri.

Now a few months after we first heard about the planet and scientists are talking up something even more interesting.

Teams of scientists believe that Proxima B might have oceans of liquid water on the surface.

The Cassinis spacecraft's farewell tour of Saturn may be focused on the strangely empty space between the planet and its rings, but it's still taking time to do some local sightseeing.

Cassini snapped this image of Saturn's largest moon Titan on May 7 from a distance of 303,000 miles (488,000 kilometers) away.

The bright streaks are methane clouds, while the darker splotches seen toward the top are the moon's fascinating hydrocarbon lakes.

NASA released two versions of the image on Tuesday with different levels of enhancement.

One makes the bands and seas really pop out, while the other offers a softer, more ethereal view of the same scene.

The Cassini mission, which launched in 1997, is scheduled to end in September when the spacecraft will destroy itself in Saturn's atmosphere.

You could start by cutting down your paper use, especially now that Sony has a new, enormous E Ink tablet on the market.

Replacing paper comes at a high cost — at least initially.

Sony has been trying to get you off of tree pulp for quite some time now, but unless you have money to blow, you may not be so enticed by the latest epaper tablet.

It’s called the DPT-RP1, and while it promises tons of high-tech features (and yes, the ability to help save the planet), it comes with a high price tag, too — $700.

In many ways, the new tablet is similar to Sony’s DPT-S1 reader, which was first introduced back in April of 2014.

But Sony allowed users to do much more than read off their original tablets — rather, this was a digital notebook with 4 GB of memory.

Parts of Mercury s varied surface came from melted material over 200 miles deep inside the planet near the core-mantle boundary, NASA scientists found.

The tiny planet of Mercury, the closest to the Sun, has a surface that spans different ages.

The Northern Volcanic Plains date to about 3.7 or 3.8 billion years ago, while another region dates to over 4 billion years of age.

In order to better understand how the planet s surface got to be the way it is, scientists conducted research on Earth, subjecting a chemical mix to high pressures.

From those experiments, the scientists discovered that the older parts of Mercury s surface formed deep inside the planet.

The Saturn-studying Cassini spacecraft triumphed through its first daring dive between the planet and its famous rings on Wednesday.

The craft shot through the narrow gap and came within 1,900 miles (3,000 kilometers) of Saturn's clouds.

"No spacecraft has ever been this close to Saturn before," Cassini Project Manager Earl Maize of NASA said.

"We could only rely on predictions, based on our experience with Saturn's other rings, of what we thought this gap between the rings and Saturn would be like."

Maize added that Cassini came through "in excellent shape."

On Thursday, NASA released several unprocessed images captured during the flight, which give us our closest-ever view of Saturn's atmosphere.

Placed on Earth, it would stretch from Washington DC to New York to Detroit.

Larger than the Grand Canyon, wider and deeper than East Africa s Great Rift Valley, Mercury s newly-discovered Great Valley boggles the imagination.

But it s more than size that makes this geologic feature remarkable.

A few months back, scientists analyzing data collected during NASA s MESSENGER mission made a startling announcement: Mercury, a planet just a smidge larger than our Moon that sits blisteringly close to the Sun, is geologically active.

Based on numerous tiny fault scarps scattered across the planet s surface, scientists determined that Mercury is undergoing crustal shrinking, a form of tectonic activity, as its core cools.

Not by much, but by enough that a future mission can measure it, test Albert Einstein’s landmark theory of general relativity, and further refine its mathematics

Mercury’s importance is far greater than its small size might imply—it’s one of the hallmark tests of Einstein’s hugely important theory of general relativity, for example.

So you don’t accuse of me of overselling things here, I’ll be frank: It’s not a huge discrepancy.

“This is a tiny effect compared to the usually quoted relativistic correction,” Konstantin Batygin, a Caltech planetary astrophysicist who was not involved in the paper told me.

“But an interesting development nonetheless.”

Thanks to the gravitational pull of the other planets, Mercury precesses in its orbit, meaning it draws out a spirograph around the sun—the closest point in its elliptical orbit moves slowly around the Sun in a circle.
