Explore nasa's Instagram Brrrr! Our James Webb Space Telescope will be very cold during the hot Houston summer inside our Johnson Space Center’s historic Chamber A as it undergoes its final three months of testing in a cryogenic vacuum that mimics the cold temperatures of space. Chamber A will chill down to simulate a space environment of extreme cold -- around 37º Kelvin (-236ºC/-393ºF). In space, the telescope must be kept extremely cold, in order to be able to detect the infrared light from very faint, distant objects. To protect the telescope from external sources of light and heat (like the sun, Earth, and moon), as well as from heat emitted by the observatory, a five-layer, tennis court-sized sunshield acts like a parasol that provides shade. The sunshield separates the observatory into a warm, sun-facing side (reaching temperatures close to 400ºF) and a cold side (-185ºF). The sunshield blocks sunlight from interfering with the sensitive telescope instruments.

The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built.

Explore nasa's Instagram We're working to understand why up to 10 million jets of solar material burst from the sun’s surface at any moment. Called spicules, they can erupt as fast as 60 miles per second and reach lengths of 6,000 miles before collapsing. Now, for the first time, a computer simulation — so detailed it took a full year to run — shows how spicules form, helping scientists understand how they break free of the sun’s surface and surge upward so quickly. Observing spicules has been a thorny problem for scientists, because spicules are transient, forming and collapsing over the course of just five to 10 minutes. These tenuous structures are also difficult to study from Earth, where the atmosphere often blurs our telescopes’ vision. This work relied upon high-cadence observations from our Interface Region Imaging Spectrogragh, or IRIS,  and the Swedish 1-meter Solar Telescope in La Palma, in the Canary Islands. Together, the spacecraft and telescope peer into the lower layers of the sun’s atmosphere, known as the interface region, where spicules form.

Explore nasa's Instagram Swirling bands of light and dark clouds on Jupiter are seen in this image made by citizen scientists using data from our Juno spacecraft. Each of the alternating light and dark atmospheric bands in this image is wider than Earth, and each rages around Jupiter at hundreds of miles (km) per hour. The lighter areas are regions where gas is rising, and the darker bands are regions where gas is sinking. This image was acquired on May 19, 2017 from about 20,800 miles (33,400km) above Jupiter's cloud tops.

Explore nasa's Instagram Over the weekend, engineers on the ground remotely operated the International Space Station’s robotic arm to remove the Roll-Out Solar Array (ROSA) from the trunk of SpaceX’s Dragon cargo vehicle. Here, you see the experimental solar array unfurl as the station orbits Earth. 
Solar panels are an efficient way to power satellites, but they are delicate and large, and must be unfolded when a satellite arrives in orbit. The Roll-Out Solar Array (ROSA) is a new type of solar panel that rolls open in space like a party favor and is more compact than current rigid panel designs.

ROSA is 20% lighter and 4x smaller in volume than rigid panel arrays! 
This experiment will remain attached to the robotic arm over seven days to test the effectiveness of the advanced, flexible solar array that rolls out like a tape measure. During this time, we will also measure power produced by the array and monitor how the technology handles retraction.

Explore nasa's Instagram [Artist Rendering] Our Kepler Space Telescope team has identified 219 new planet candidates, 10 of which are near-Earth size and in their respective star’s habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. This illustration is based on data of one of thousands of planets beyond the solar system, called exoplanets, that Kepler has detected. These other worlds vary widely in size and orbital distances, showing us that most stars are home to at least one planet. Kepler continues the search for exoplanets and the study of notable star clusters, young and old stars, active galaxies and supernovae.

Glowing like a multifaceted jewel, this nebula will gradually disperse into space over the next several thousand years, and then the star will cool and fade away for billions of years as a white dwarf. 
Our own sun is expected to undergo a similar fate, but fortunately, this will not occur until some 5 billion years from now.

Explore nasa's Instagram Two dozen scientists and members of our New Horizons spacecraft team ventured to Argentina and South Africa hoping to capture the fleeting starlit shadow of 2014 MU69 overnight on June 2-3, 2017 as MU69 passed in front of a distant star. MU69 is the target that the New Horizons spacecraft will explore in a flyby on New Year’s Day 2019.

Swipe to see the teams in action in Argentina and South Africa as they collected data on the stellar occultation of MU69. It was reported that all 54 telescope teams collected data and that team scientists started digging into that data when they returned home after the observations. The main goal of these observations was to search for hazards to the spacecraft, while the teams also tried to glimpse the occultation of MU69 itself, in order to learn its precise size.

Explore nasa's Instagram Jupiter's clouds of many colors are seen in this image from our Juno spacecraft as it was racing away from the planet following its seventh close pass on May 19, 2017, from about 29,100 miles (46,900 km) above the cloud tops. 
This image was processed to enhance color differences, showing the amazing variety in Jupiter’s stormy atmosphere. The result? A surreal world of vibrant color, clarity and contrast! You’ll notice four white oval storms are visible near the top of the image, known as the “String of Pearls”. Interestingly, one orange-colored storm can be seen at the belt-zone boundary, while other storms are more of a cream color.

Explore nasa's Instagram Get outside and see what’s up in the night sky! On June 15, Saturn reaches opposition, which is when Saturn, Earth and the sun are all in a straight line, with Earth in the middle. Opposition provides the best and closest views of the ringed planet and several of its brightest moons. 
If you see just one, that’s Titan. Titan is 50% larger than our own moon and orbits Saturn about every 16 Earth days. Through a telescope you’ll be able to compare the cloud bands on both Saturn and Jupiter.

Explore nasa's Instagram Today is #FlagDay, commemorating the adoption of the United States flag, which took place on June 14, 1777. Seen here is the American flag in one of the windows of the International Space Station's (@iss) cupola, a dome-shaped module through which operations on the outside of the station can be observed and guided. Astronaut Jack Fischer took this photograph and shared it on social media.

Throughout NASA's history, spacecraft and launch vehicles have always been decorated with flags. When Ed White became the first American astronaut to perform a spacewalk on June 3, 1965, his spacesuit was one of the first to be adorned with a flag patch. White's crewmate Jim McDivitt also wore a flag on his suit. The astronauts purchased the flags themselves, but following their flight, NASA made the flag patch a regular feature on the spacesuits. NASA astronauts still wear them today.

Explore nasa's Instagram In biology, “symbiosis” refers to two organisms that live close to and interact with one another. There happens to also be a class of stars that co-exist in a similar way. Data from our Chandra X-ray Observatory and other telescopes, is helping us understand how volatile this close stellar relationship can be.

Located at a distance of about 710 light years from Earth, R Aquarii (R Aqr, for short) is one of the best known of the symbiotic stars. Changes in its brightness were first noticed with the naked eye almost a thousand years ago. Since then, astronomers have studied this object and determined that R Aqr is not one star, but two: a small, dense white dwarf and a cool red, giant star. 
Since shortly after Chandra launched in 1999, astronomers began using the X-ray telescope to monitor the behavior of R Aqr, giving them a better understanding in more recent years. Chandra data reveal a jet of X-ray emission that extends to the upper left. The X-rays have likely been generated by shock waves, similar to sonic booms around supersonic planes, caused by the jet striking surrounding material.

Applicants included U.S. citizens in all 50 states, the District of Columbia, and U.S. territories Puerto Rico, Guam and America Samoa. The talented women and men selected for the new astronaut class represent the diversity of America and the career paths that can lead to a place in America’s astronaut corps.

Explore nasa's Instagram A pair of relatively small active regions rotated into view of our solar observatory May 31 – June 2, spouting off numerous small flares and sweeping loops of plasma. At first, only the one active region was observed, but mid-way through the video clip a second one behind the first can be picked out. The dynamic regions were easily the most remarkable areas on the sun during this 42-hour period. 
The images were taken in a wavelength of extreme ultraviolet light.

Explore nasa's Instagram Jagged spikes, speckled noise and weird, clashing colors…what does this Hubble Space Telescope image show? A distant galaxy, visible as the smudge to the lower right, as it begins to align and pass behind a star sitting nearer to us within the Milky Way. This is an event known as a transit and can tell us a lot about these celestial objects.
