Stellar Fireworks! Resembling an aerial fireworks explosion, this dramatic image of the energetic star WR124, taken by the Hubble Space Telescope, reveals that it is surrounded by hot clumps of gas being ejected into space at speeds of over 100,000 miles per hour. The picture was taken in March 1997. The image is false-colored to reveal details in the nebula's structure.

Extraterrestrial Fireworks on this Independence Day! Reminiscent of a fireworks celebration, this Hubble Space Telescope image of a cosmic explosion that is quite similar to fireworks on Earth. In the upper right corner of the image, the Small Magellanic Cloud is a delicate glowing structure ablaze in a multitude of lavenders and peach. Nearby, a massive star has exploded as a supernova and begun to dissipate its interior into a spectacular display of colorful filaments. Determined to be only about 2,000 years old, young supernova remnants like this allow astronomers to examine material from the cores of massive stars directly. This in turn gives insight on how stars form, their composition and the chemical enrichment of the surrounding area. As well, young remnants are a great learning tool to better understand the physics of supernova explosions. The Small Magellanic Cloud is a nearby dwarf galaxy to our own Milky Way. It is visible in the Southern Hemisphere, in the direction of the constellation Tucana, and lies roughly 210,000 light-years distant.

Celestial Fireworks! Resembling the puffs of smoke and sparks from Independence Day fireworks display, this Hubble image depicts the delicate filaments debris from a stellar explosion in a neighboring galaxy. Denoted N 49, or DEM L 190, this remnant is from a massive star that died in a supernova blast whose light would have reached Earth thousands of years ago. This filamentary material will eventually be recycled into building new generations of stars. Our own sun and planets are constructed from similar debris of supernovae that exploded in the Milky Way billions of years ago.

The 'Fireworks Galaxy' - NGC 6946 is a medium-sized, face-on spiral galaxy about 22 million light years away from Earth. In the past century, eight supernovas have been observed to explode in the arms of this galaxy. Chandra observations (purple) have, in fact, revealed three of the oldest supernovas ever detected in X-rays, giving more credence to its nickname of the "Fireworks Galaxy." This composite image also includes optical data from the Gemini Observatory in red, yellow, and cyan.

Happy Independence Day! Here's a red, white and blue image of Earth. Our Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft zipped around Earth, getting an orbit correction from Earth's gravity and getting a chance to test its instruments by observing its home planet. The wide-angle camera records light at eleven different wavelengths, including visible and infrared light. Combining blue, red, and green light results in a true-color image from the observations. The image substitutes infrared light for blue light in the three-band combination. The resulting image is crisper than the natural color version because our atmosphere scatters blue light. Infrared light, however, passes through the atmosphere with relatively little scattering and allows a clearer view. That wavelength substitution makes plants appear red. Why? Plants reflect near-infrared light more strongly than either red or green, and in this band combination, near-infrared is assigned to look red.

Red, white and blue from the International Space Station to you! Astronauts aboard the space station captured this photo of Earth's atmospheric layers on July 31, 2011, revealing the troposphere (orange-red), stratosphere and above. Satellite instruments allow scientists to better understand the chemistry and dynamics occurring within and between these layers.

Fireworks! Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106. Energetic jets, which blast from Messier 106's central black hole, are heating up material in the galaxy and thus making it glow, like the ingredients in a firework. The jets also power shock waves that are driving gases out of the galaxy's interior. A galaxy about 23 million light years away is the site of this impressive, ongoing fireworks. Rather than paper, powder and fire, this galactic light show involves a giant black hole, shock waves and vast reservoirs of gas. This galactic fireworks display is taking place in NGC 4258, also known as M106, a spiral galaxy like the Milky Way. This galaxy is famous, however, for something that our galaxy doesn't have - two extra spiral arms that glow in X-ray, optical and radio light. These features, or anomalous arms, are not aligned with the plane of the galaxy, but instead intersect with it.

Infrared View of a Comet and Distant Galaxy: Our NEOWISE mission captured this series of pictures of comet C/2012 K1 -- also known as comet Pan-STARRS -- as it swept across our skies on May 20, 2014. The comet is relatively close to us -- it was only about 143 million miles (230 million kilometers) from Earth when this picture was taken. It is seen passing a much more distant spiral galaxy, called NGC 3726, which is about 55 million light-years from Earth, or 2 trillion times farther away than the comet.

Tropical Storm Arthur churns in the Atlantic: The storm's center was east of Florida's northeast coast. By 5 a.m. EDT on July 3, Arthur's eye had formed but remained cloud covered even as the storm hit hurricane-strength with maximum sustained winds near 75 mph. This visible image of Tropical Storm Arthur was taken by the MODIS instrument aboard NASA's Aqua satellite on July 2 at 18:50 UTC (2:50 p.m. EDT). A cloud-covered eye is clearly visible.

Tropical Storm Arthur appears to be ramping up, and astronaut Reid Wiseman aboard the space station captured this image and wrote, "Just flew over TS #Arthur - hoping it heads to sea. Looks mean." Heavy rains are expected to affect the southern U.S. coastline over the next several days as the National Hurricane Center expects Arthur to strengthen into a hurricane. On July 2, the NHC issued a Hurricane Watch for Bogue Inlet to Oregon Inlet, North Carolina and Pamlico Sound. In addition, a Tropical Storm Watch is in effect for the east coast of Florida from Sebastian Inlet to Flagler Beach, South Santee River South Carolina to south of Bogue Inlet, North Carolina, north of Oregon Inlet, North Carolina to the North Carolina/Virginia Border, and the Eastern Albemarle Sound.

NASA’s Orbiting Carbon Observatory-2 (OCO-2) spacecraft is safely in space, successfully deployed its solar arrays and is processing power. OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural “sinks” that absorb carbon dioxide and help control its buildup. The observatory will measure the global geographic distribution of these sources and sinks and study their changes over time. Seen here is the United Launch Alliance Delta II rocket launching with the Orbiting Carbon Observatory-2 satellite onboard from Space Launch Complex 2 at Vandenberg Air Force Base, Calif. on Wednesday, July 2, 2014.

Live coverage of the launch of NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission is underway from Vandenberg Air Force Base in California, where preparations for the liftoff of ULA’s Delta II rocket carrying OCO-2 to space are happening. Launch is targeted for the opening of a 30-second window at 5:56:23 a.m. EDT (2:56:23 a.m. PDT) from Space Launch Complex 2. There is a 100 percent chance of favorable weather for launch with no range safety launch commit criteria violations predicted. Visibility is forecast to be 1-2 miles with fog and a northerly wind of 4-7 knots. Based on the weather forecast and no technical issues, NASA Launch Manager Tim Dunn has given a “go” to load liquid oxygen into the Delta II rocket first stage at Space Launch Complex 2. The launch team has completed troubleshooting a water suppression system issue that resulted in the scrub of a launch attempt Tuesday. A valve that is part of the launch pad pulse suppression water system, which had operated properly during tests shortly before the countdown, failed to function properly during the final minute before launch. The failed valve was replaced with a spare and the system was retested in preparation for today’s launch attempt. OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth’s climate. OCO-2 will provide a new tool for understanding the human and natural sources of carbon dioxide emissions and the natural “sinks” that absorb carbon dioxide and help control its buildup. The observatory will measure the global geographic distribution of these sources and sinks and study their changes over time.

Twas the night before launch... Our Orbiting Carbon Observatory-2 (OCO-2) is perched atop a United Launch Alliance Delta II rocket, which is scheduled to launch Wednesday at 5:56 a.m. EDT (2:56 a.m. PDT) from Space Launch Complex 2 at Vandenberg Air Force Base in California. The OCO-2 mission will produce the most detailed picture to date of natural sources of carbon dioxide, as well as their "sinks" -- places on Earth’s surface where carbon dioxide is removed from the atmosphere. The observatory will study how these sources and sinks are distributed around the globe and how they change over time.
