Check out features of our feline friends that have come to life as interstellar phenomena! 

Pictured first, the Cat’s Paw Nebula is located about 4,200-5,500 light-years from Earth – situated in our very own Milky Way Galaxy. It was named for the large, round features that create the impression of a feline footprint and was captured by our Spitzer Space Telescope. After gas and dust inside the nebula collapse to form stars, the stars may in turn heat up the pressurized gas surrounding them. This process causes the gas to expand into space and form the bright red bubbles you see. The green areas show places where radiation from hot stars collided with large molecules called “polycyclic aromatic hydrocarbons,” causing them to fluoresce.

Next, you’ll find the Cat’s Eye Nebula. Residing 3,000 light-years from Earth, the Cat’s Eye represents a brief, yet glorious, phase in the life of a sun-like star. This nebula’s dying central star may have produced the simple, outer pattern of dusty concentric shells by shrugging off outer layers in a series of regular convulsions. To create this view, Hubble Space Telescope archival image data have been reprocessed. Compared to well-known Hubble pictures, the alternative processing strives to sharpen and improve the visibility of details in light and dark areas of the nebula and also applies a more complex color palette. Gazing into the Cat’s Eye, astronomers may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution … in about 5 billion years.

#GreenNuclearDeal

"Scientists achieved high pressure plasma perhaps laying the groundwork to achieve fusion power at an old fusion reactor in San Diego by reversing the orientation of the vessel that houses the plasma."

50 years ago, three Apollo astronauts rode this 363 foot tall rocket, the Saturn V, embarking on one of the greatest missions of mankind – to step foot on another world. On July 20, 1969, astronauts Buzz Aldrin, Michael Collins and Neil Armstrong made history when they arrived at the Moon. Thanks to the Saturn V rocket, we were able to complete this epic feat, returning to the lunar surface a total of six times. The six missions that landed on the Moon returned a wealth of scientific data and almost 400 kilograms of lunar samples. 

In honor of this historic launch, the National Air and Space Museum is projecting the identical rocket that took our astronauts to the Moon on the Washington Monument in Washington, D.C.

This week, you can watch us salute our Apollo 50th heroes and look forward to our next giant leap for future missions to the Moon and Mars. Tune in to a special two-hour live NASA Television broadcast at 1 p.m. ET on Friday, July 19. Watch the program at www.nasa.gov/live.

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!

The trickster “Blinking Planetary”

Planetary nebula NGC 6826 is located about 4,200 light years from Earth in Cygnus. When observers look directly at it through a small telescope, they typically see only the nebula’s sparkling-white central star. However, by averting one’s gaze, glancing away from the central star, the nebula’s bulbous dust clouds come into view. This optical trickery earned this planetary nebula the name the “Blinking Planetary.” 

Over the next several thousand years, the nebula will gradually disperse into space, and then the central star will slowly cool as it radiates its energy for billions of years as a white dwarf.

Our Eyes in the Sky See Toxic Waters

Warm summer temperatures often lead to dangerous blooms of phytoplankton in lakes, reservoirs and along our coastlines. These toxin-containing aquatic organisms can sicken people and pets, contaminate drinking water, and force closures at boating and swimming sites.

In this image, a severe bloom of toxic blue-green algae is spreading across the western half of Lake Erie. Taken on July 30, 2019 by the Operational Land Imager on our Landsat 8 satellite, this image shows green patches where the bloom was most dense and where toxicity levels were unsafe for recreational activities. Around the time of this image, the bloom covered about 300 square miles of Lake Erie’s surface, roughly the size of New York City. By August 13, the bloom had doubled to more than 620 square miles. That’s eight times the size of Cleveland. 

The dominant organism—a Microcystis cyanobacteria—produces the toxin microcystin, can cause liver damage, numbness, dizziness, and vomiting. On July 29, 2019, the National Oceanic Atmospheric Administration (NOAA) reported unsafe toxin concentrations in Lake Erie and have since advised people (and their pets) to stay away from areas where scum is forming on the water surface.

You can stay informed about harmful algal blooms using a new mobile app that will send you alerts on potentially harmful algal blooms in your area. Called CyAN, it’s based on NASA satellite data of the color changes in lakes and other bodies of water. It serves as our eye-in-the-sky early warning system, alerting the public and local officials to when dangerous waters may be in bloom.

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.
