Hearing a lot about ocean worlds today? Let’s dive in and see what this news is all about...

We once thought oceans made our planet unique, but we’re now coming to realize that ‘ocean worlds’ are all around us.

Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other ‘ocean worlds’ in our solar system and beyond. The findings are presented in papers published Thursday by researchers with our Cassini mission to Saturn and Hubble Space Telescope.

A patchwork of bright, criss-crossing cloud trails was created by ships churning through the Atlantic Ocean off the coast of Portugal and Spain in this image captured by one of our Earth observing satellites. The narrow clouds known as ship tracks, form when water vapor condenses around tiny particles of pollution that ships emit.

Some of the pollution particles generated by ships (especially sulfates) are soluble in water and serve as the seeds around which cloud droplets form. Clouds infused with ship exhaust have more and smaller droplets than unpolluted clouds. Because of this, the light hitting the polluted clouds scatters in many directions, making them appear brighter and thicker than unpolluted marine clouds, which are typically seeded by larger, naturally occurring particles such as sea salt.

What’s Up for August 2016

What’s up for August? How to spot Mercury, Venus,  Mars, Jupiter and Saturn, as well as the and the annual Perseid meteor shower. 

Here are some highlights in this month’s nighttime skies as picked by astronomer Jane Houston Jones from our Jet Propulsion Laboratory.

Spot Venus, Mercury and Jupiter and the moon low on the western horizon about 45 minutes after sunset from August 4 through 7. On August 11, look in the south-southwest sky for a second planetary dance as Mars and Saturn are high and easy to see and they are joined by the moon.

The famous and reliably active Perseid meteor shower peaks in the morning hours of August 12. The moon, which paired up so nicely with Mars and Saturn on the 11, is bright enough to blot out some of the meteors, but lucky for you it sets about 1 a.m. on the morning of the 12, just at the peak time for the best Perseid viewing.

But wait, there are more planets, dwarf planets and an asteroid visible this month! Uranus and Neptune and dwarf planet Ceres are visible before dawn in the southern sky. Uranus is visible through binoculars but Neptune and Ceres require a telescope.

Secrets lie deep within Jupiter, shrouded in the solar system's strongest magnetic field and most lethal radiation belts. On July 4, 2016, our Juno spacecraft will plunge into uncharted territory, entering orbit around the gas giant and passing closer than any spacecraft before. Juno will see Jupiter for what it really is, but first it must pass the trial of orbit insertion. For more information: http://www.nasa.gov/juno and http://missionjuno.swri.edu.

What are three things you would want everyone to know about your work?

Black (Hole) Friday!

It’s Black Friday, but for us, it’s the annual Black Hole Friday! Today, we’ll post awesome images and information about black holes.

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space…sort of like all of those shoppers trying to fit into the department stores today.

Because no light can get out, you can’t see black holes with the naked eye. Space telescopes with special tools help find black holes (similar to how those websites help you discover shopping deals).

How big are black holes? Black holes can be large or small…just like the lines in all of the stores today. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain! 

So how do black holes form? Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star collapses. When this happens, it causes a supernova. 

A supernova is an exploding star that blasts part of its mass into space. 

Supermassive black holes are an altogether different story. Scientists think they were made at the same time as the galaxy they in they reside. Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. 

When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed -- or "spaghettified" -- as the black hole swallows it. A black hole destroying a star, an event astronomers call "stellar tidal disruption," releases an enormous amount of energy, brightening the surroundings in an event called a flare. In recent years, a few dozen such flares have been discovered.

Then there are ultramassive black holes, which are found in galaxies at the centers of massive galaxy clusters containing huge amounts of hot gas.

Have a Happy Halloween with NASA

Attention ghouls and goblins of the galaxy! The season for scares and frights is upon us, so we’ve rounded up a few Halloween resources to capture that festive feeling. Read on for craft ideas, free decoration downloads, a creepy soundtrack, and even costume ideas.

Overdid it at the pumpkin patch this year? Get some creative inspiration and some pumpkin-building tips from our Jet Propulsion Laboratory engineers, carve a James Webb Space Pumpkin, or paint a pumpkin with space and weather themed designs. And yes – you can make a NASA pumpkin, too.

Speaking of design, check out our terrifying Galaxy of Horrors posters: decorate your walls with a an illustration of a galactic graveyard or of dark energy prowling through the universe…

If costumes are more your thing, see how the astronauts aboard the International Space Station have dressed up over the years.

Finally, our Sinister Sounds of the Solar System playlist will give you just the right soundtrack for a haunted house or a party – or for scaring yourself all alone.

Does all capsules drops in Kazakhstan on return after every mission?

Since the US Space Shuttle retired in 2011, we launch to and return from the Space Station with the Russian Space Agency.  So yes, these capsules (the Soyuz) land in Kazakhstan (or surrounding regions).  However, different spacecrafts have different reentry trajectories, depending on where they aim to land.  As you might recall, the Apollo mission capsules landed in the ocean.  Since Space-X and Boeing are currently building new vehicles so that we will also launch from the US again to get to the International Space Station, these spacecraft will return to the US. For example, you may have seen footage of Space-X cargo vehicles splashing down into the Pacific over the last few years. The Boeing Starliner plans to land on land instead of water. NASA is also currently building the Orion spacecraft, which will take us to destinations beyond low earth orbit (where the Space Station is), whether that be the Moon or Mars or another target.  Orion will also splash down in the ocean.  

You’ve seen things floating in space, but why does that happen and how does it affect science being conducted aboard the International Space Station?

Sure, floating looks like fun, but it could also unlock new scientific discoveries!

Microgravity makes the International Space Station the perfect place to perform research that is changing the lives of people on Earth, and preparing us to go deeper into space. This season on our series NASA Explorers, we are following science into low-Earth orbit and seeing what it takes to do research aboard the space station.
