Say hello to the Antennae galaxies 👋

Two galaxies are locked in a deadly embrace in this Hubble image. Once normal, sedate spiral galaxies like the Milky Way, this galactic pair has spent the past few hundred million years sparring. The clash is so violent that stars have been ripped from their host galaxies to form a streaming arc between the two. 

The far-flung stars and streamers of gas stretch out into space, creating long tidal tails reminiscent of antennae (not visible in this close-up Hubble view). Clouds of gas blossom out in bright pink and red, surrounding the bright flashes of blue star-forming regions — some of which are partially obscured by dark patches of dust. 

Hubble’s observations have uncovered over 1,000 bright, young star clusters bursting to life as a result of the head-on wreck. The sweeping spiral-like patterns, traced by bright blue star clusters, shows the result of a firestorm of star-birth activity, which was triggered by the collision. The rate of star formation is so high that the Antennae galaxies are said to be in a state of starburst, a period in which all of the gas within the galaxies is being used to form stars. This cannot last forever, and neither can the separate galaxies; eventually the nuclei will coalesce and the galaxies will begin their retirement together as one large elliptical galaxy.

Computational modeling of fusion plasmas is very challenging: scales to be covered range from micrometers to meters and picoseconds to minutes. With largest supercomputers available, our understanding was pushed forward by modelling and still is.

Be Glad You Don’t Have to Dust in Space!

Throw open the windows and break out the feather duster, because spring is here and it’s time to do a little cleaning! Fortunately, no one has to tidy up the dust in space — because there’s a lot of it — around 100 tons rain down on Earth alone every day! And there’s even more swirling around the solar system, our Milky Way galaxy, other galaxies and the spaces in between. 

By studying the contents of the dust in your house — which can include skin cells, pet fur, furniture fibers, pollen, concrete particles and more — scientists learn a lot about your environment. In the same way, scientists can learn a lot by looking at space dust. Also called cosmic dust, a fleck of space dust is usually smaller than a grain of sand and is made of rock, ice, minerals or organic compounds. Scientists can study cosmic dust to learn about how it formed and how the universe recycles material.

“We are made of star-stuff,” Carl Sagan famously said. And it’s true! When a star dies, it sheds clouds of gas in strong stellar winds or in an explosion called a supernova. As the gas cools, minerals condense. Recent observations by our SOFIA mission suggest that in the wake of a supernova shockwave, dust may form more rapidly than scientists previously thought. These clouds of gas and dust created by the deaths of stars can sprawl across light-years and form new stars — like the Horsehead Nebula pictured above. Disks of dust and gas form around new stars and produce planets, moons, asteroids and comets. Here on Earth, some of that space dust eventually became included in living organisms — like us! Billions of years from now, our Sun will die too. The gas and dust it sheds will be recycled into new stars and planets and so on and so forth, in perpetuity!

Astronomers originally thought dust was a nuisance that got in the way of seeing the objects it surrounded. Dust scatters and absorbs light from stars and emits heat as infrared light. Once we started using infrared telescopes, we began to understand just how important dust is in the universe and how beautiful it can be. The picture of the Andromeda galaxy above was taken in the infrared by our Spitzer Space Telescope and reveals detailed spirals of dust that we can’t see in an optical image.

We also see plenty of dust right here in our solar system. Saturn’s rings are made of mostly ice particles and some dust, but scientists think that dust from meteorites may be darkening the rings over time. Jupiter also has faint dusty rings, although they’re hard to see — Voyager 1 only discovered them when it saw them backlit by the Sun. Astronomers think the rings formed when meteorite impacts on Jupiter’s moons released dust into orbit. The Juno spacecraft took the above picture in 2016 from inside the rings, looking out at the bright star Betelgeuse.

And some space dust you can see from right here on Earth! In spring or autumn, right before sunrise or after sunset, you may be able to catch a glimpse of a hazy cone of light above the horizon created when the Sun’s rays are scattered by dust in the inner solar system. You can see an example in the image above, extending from above the tree on the horizon toward a spectacular view of the Milky Way. This phenomenon is called zodiacal light — and the dust that’s reflecting the sunlight probably comes from icy comets. Those comets were created by the same dusty disk that that formed our planets and eventually you and the dust under your couch!

5 Out-of-this-world Facts About Our Iconic Vehicle Assembly Building!

The Vehicle Assembly Building, or VAB, at our Kennedy Space Center in Florida, is the only facility where assembly of a rocket occurred that carried humans beyond low-Earth orbit and on to the Moon. For 30 years, its facilities and assets were used during the Space Shuttle Program and are now available to commercial partners as part of our agency’s plan in support of a multi-user spaceport. To celebrate the VAB’s continued contribution to humanity’s space exploration endeavors, we’ve put together five out-of-this-world facts for you!

1. It’s one of the largest buildings in the world by area, the VAB covers eight acres, is 525 feet tall and 518 feet wide.

Unveiling the Center of Our Milky Way Galaxy

We captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.

Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.

The new view was made by the world’s largest airborne telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA.

4. Spitzer Celebrates its Super Sweet 16! 

Since 2003, our Spitzer Space Telescope has been lifting the veil on the wonders of the cosmos, from our own solar system to faraway galaxies, using infrared light! Thanks to Spitzer, we’ve confirm the presence of seven rocky, Earth-size planets, received weather maps of hot, gaseous exoplanets and discovered a hidden ring around Saturn. In honor of Spitzer’s Sweet 16 in space, enjoy 16 jaw-dropping images from its mission here. 

5. Earth as Seen Through Our Astronauts’ Eyes Show  Perspective Changing Views

“That’s here. That’s home. That’s us.” – Carl Sagan

Seeing Earth from space can alter an astronauts’ cosmic perspective, a mental shift known as the “Overview Effect.” First coined by space writer Frank White in 1987, the Overview Effect is described as a feeling of awe for our home planet and a sense of responsibility for taking care of it. See Earth from the vantage point of our astronauts in a carousel of perspective-changing views here.

6. Astronaut Christina Koch Breaks Records With 300 Days in Space 

Astronaut Christina Koch (@Astro_Christina) set a record Dec. 28, 2019 for the longest single spaceflight by a woman, eclipsing the former record of 288 days set by Peggy Whitson. Her long-duration mission is helping us learn how to keep astronauts healthy for deep space exploration to the Moon and Mars. Congrats to Christina on reaching new heights! Join in the celebration and view few photos she captured from her vantage point aboard the Space Station here.
