The Trapezium is that a space ghost?

Using the advanced adaptive optics system on the Gemini South telescope, astronomers have imaged a beautiful stellar jewel-box – a tightly packed cluster of stars that is one of the few places in our galaxy where astronomers think stars can actually collide. Stellar collisions are important because they can provide the key to understand the origin of exotic objects that cannot be interpreted in terms of the passive evolution of single stars. read more here credit: Gemini Observatory/AURA

An Airglow Fan from Lake to Sky 

Why would the sky look like a giant fan? Airglow. The featured intermittent green glow appeared to rise from a lake through the arch of our Milky Way Galaxy, as captured last summer next to Bryce Canyon in Utah, USA. The unusual pattern was created by atmospheric gravity waves, ripples of alternating air pressure that can grow with height as the air thins, in this case about 90 kilometers up. Unlike auroras powered by collisions with energetic charged particles and seen at high latitudes, airglow is due to chemiluminescence, the production of light in a chemical reaction. More typically seen near the horizon, airglow keeps the night sky from ever being completely dark.

hubble’s panorama of the carina nebula, some 7500 light years away from earth, and about fifty light years in length here. stars old and new illuminate clouds of cosmic dust and gas, like the clumping hydrogen from which they were born. 

the top star seen at the bisection of the first two panels, part of the eta carinae binary star system (most stars are in binary systems), is estimated  to be more than a hundred times the mass of the sun - large enough to go supernoava in about a million years. 

it also produces four million times as much light as the sun, and was once the second brightest star in the night sky. but surrounding dust and gas has dimmed our view of the star, though it’s still visible in the night sky to all but those in the most light polluted cities.

the fifth panel shows ‘the mystic mountain,’ where nascent stars in the dust cloud are spewing hot ionized gas and dust at 850,000 miles an hour. eventually, the ultraviolet radiation from these stars will blow away the dust, leaving visible the stars, like the cluster seen at the top of the panel, which were formed only half a million years ago.

Mars Pathfinder & Sojourner Rover (360 View) Explained

Thanks to new technology, we can take a 360-degree tour of the 1997 Pathfinder mission landing site, including Sojourner, the first Mars rover. Check out this interactive YouTube panorama, and then…

…keep scrolling to find out more about each point of interest, how the Pathfinder mission compares to “The Martian” and NASA’s real Journey to Mars.

Yogi

“Yogi” is a meter-size rock about 5 meters northwest of the Mars Pathfinder lander and the second rock visited by the Sojourner Rover’s alpha proton X-ray spectrometer (APXS) instrument. This mosaic shows super resolution techniques applied to help to address questions about the texture of this rock and what it might tell us about how it came to be.

Twin Peaks

The Twin Peaks are modest-size hills to the southwest of the Mars Pathfinder landing site. They were discovered on the first panoramas taken by the IMP camera on the July 4, 1997, and subsequently identified in Viking Orbiter images taken over 20 years ago. They’re about 30-35 meters tall.

Barnacle Bill

“Barnacle Bill” is a small rock immediately west-northwest of the Mars Pathfinder lander and was the first rock visited by the Sojourner Rover’s alpha proton X-ray spectrometer (APXS) instrument. If you have some old-school red-cyan glasses, put them on and see this pic in eye-popping 3-D.

Rock Garden

The Rock Garden is a cluster of large, angular rocks tilted in a downstream direction from ancient floods on Mars. The rocky surface is comprised of materials washed down from the highlands and deposited in this ancient outflow channel.

Colors of Earth

When we think of our globe from a distance, we generally visualize two colors: blue and green. Water and land. Mostly water, consequently, our planet’s nickname of the blue marble.

Traveling around the globe every 90 minutes covering millions of miles with a focused lens on our beautiful planet from 250 miles above, I’ve captured many beautiful colors beyond blue and green that showcase Earth in new and interesting ways. Some colors are indicative of nature like desert sands and weather like snow. Other colors tell stories of Earth’s climate in bright splashes of yellows and greens of pollen and muted grey tones and clouded filters of pollution.

Blue and green still remain vivid and beautiful colors on Earth from the vantage point of the International Space Station, but here are some other colors that have caught my eye from my orbital perspective.

What’s Up for March 2016?

In March, Jupiter, it’s moons and moon shadows will all be visible in the sky. Find out when and where to look up:

Jupiter dominates the evening sky this month, rising at sunset and setting at dawn. On March 8, Jupiter reaches what is called “opposition”. Imagine that Jupiter and the sun are at opposite ends of a straight line, with the Earth in between. This brings Jupiter its closest to Earth, so it shines brighter and appears larger in telescopes.

On the nights of March 14 – 15, March 21 – 22 and March 29, two of Jupiter’s moons will cross the planet’s disk. 

When the planet is at opposition and the sun shines on Jupiter’s moons, we can see the moon’s shadow crossing the planet. There are actually 11 of these double shadow transits in March!

The next six months will be awesome times for you to image Jupiter when it’s highest in the sky; near midnight now, and a little earlier each night through the late summer.

Even through the smallest telescopes or binoculars, you should be able to see the two prominent belts on each side of Jupiter’s equator made up of the four Galilean moons: Io, Europa Ganymede and Calisto. If you have a good enough view, you may even see Jupiter’s Red Spot!

Our Juno spacecraft will arrive at Jupiter on July 4th of this year and will go into orbit around the giant planet. Right now, the Juno mission science team is actively seeking amateur and professional images of the planet. These images are uploaded to a Juno website, and the public is invited to discuss points of interest in Jupiter’s atmosphere.

Locations will later be voted on and the favorites will be targets for JunoCam, the spacecraft’s imaging camera. Once JunoCam has taken the images, they’ll be posted online. Imaging participants can then process these raw mission images and re-upload them for others to view.

Scientists are getting closer to finding the ninth planet

California Institute of Technology scientists shocked the world when they announced the possible existence of a ninth planet in our solar system earlier this year. The only problem is the finding is based on a mathematical model, not on direct observation. The planet orbits so far out on the fringes of our solar system that it likely takes up to 20,000 years to make it around the sun. Spotting it will be like looking for a needle in a haystack. But that haystack just got a bit smaller.

Fun Moments with Our Record Breaking Astronaut

Astronaut Scott Kelly has broken the record for longest time spent in space by a U.S. astronaut. He has spent a cumulative of 383 days in space over the course of four missions. What better way to celebrate than to highlight some of his fun moments on the internet:

A question from the president during a recent TweetChat:

Astronaut Scott Kelly occasionally hosts TweetChats from the International Space Station. During a recent chat, he happened to get a question from someone who lives at 1600 Pennsylvania Avenue! HERE’s a recap from a similar chat from the station. 

Tackling the tough questions during interviews:

During an interview with Katie Couric, Kelly explained what a day on the space station is really like…including the chores he can and can’t do. 

The pros and cons of having roommates:

The International Space Station is an orbiting laboratory where an international crew live, work and conduct valuable research. 

Getting supplies from cargo ships:

Living on the space station requires food, water and supplies. All of these things, plus experiments and other essentials are delivered to the crew via cargo ship. Learn more about our commercial resupply program HERE.

What music do you listen to most?

A wide variety. I created this Spotify playlist of the songs I’ve listened to most during my Year in Space. 

How do you feel about space movies like Gravity or the Martian etc?

I thought they were great. I watched them both here aboard the International Space Station. Movie night looks like this!

Are u really in space

Yes. Really. And now I am in space over New Orleans…and now I’m over Mobile, Alabama.
