❝Imagination is our window into the future. At NASA/JPL we strive to be bold in advancing the edge of possibility so that someday, with the help of new generations of innovators and explorers, these visions of the future can become a reality. As you look through these images of imaginative travel destinations, remember that you can be an architect of the future. Click on the thumbnails…to learn more and download a free poster sized image.

This might look like a double-bladed lightsaber, but these two cosmic jets actually beam outward from a newborn star in a galaxy near you. Constructed from Hubble Space Telescope image data, the stunning scene spans about half a light-year across Herbig-Haro 24 (HH 24), some 1,300 light-years or 400 parsecs away in the stellar nurseries of the Orion B molecular cloud complex.
Hidden from direct view, HH 24’s central protostar is surrounded by cold dust and gas flattened into a rotating accretion disk. As material from the disk falls toward the young stellar object it heats up. Opposing jets are blasted out along the system’s rotation axis. Cutting through the region’s interstellar matter, the narrow, energetic jets produce a series of glowing shock fronts
This visualization provides a three-dimensional perspective on Hubble’s 25th anniversary image of the nebula Gum 29 with the star cluster Westerlund 2 at its core. The flight traverses the foreground stars and approaches the lower left rim of the nebula Gum 29. Passing through the wispy darker clouds on the near side, the journey reveals bright gas illuminated by the intense radiation of the newly formed stars of cluster Westerlund 2. Within the nebula, several pillars of dark, dense gas are being shaped by the energetic light and strong stellar winds from the brilliant cluster of thousands of stars.
Happy anniversary, Hub. Waiting patiently for Webb to take over.
Kepler-186f is the first Earth-size planet discovered in the potentially ‘habitable zone’ around another star, where liquid water could exist on the planet’s surface. Its star is much cooler and redder than our Sun. If plant life does exist on a planet like Kepler-186f, its photosynthesis could have been influenced by the star’s red-wavelength photons, making for a color palette that’s very different than the greens on Earth. This discovery was made by Kepler, NASA’s planet hunting telescope.

Star forming pillars in the Eagle Nebula, 7,000 light years from Earth, as seen by the Hubble Space Telescope’s WFPC2. January 5th, 2015 High-resolution version
This image shows the pillars as seen in visible light, capturing the multi-coloured glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust-coloured elephants’ trunks of the nebula’s famous pillars. The dust and gas in the pillars is seared by the intense radiation from young stars and eroded by strong winds from massive nearby stars. With these new images comes better contrast and a clearer view for astronomers to study how the structure of the pillars is changing over time.

By 2100, global climate change will modify plant communities covering almost half of Earth’s land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type – such as forest, grassland or tundra – toward another, according to a new NASA and university computer modeling study.
Researchers from NASA’s Jet Propulsion Laboratory and the California Institute of Technology in Pasadena, Calif., investigated how Earth’s plant life is likely to react over the next three centuries as Earth’s climate changes in response to rising levels of human-produced greenhouse gases…
The model projections paint a portrait of increasing ecological change and stress in Earth’s biosphere, with many plant and animal species facing increasing competition for survival, as well as significant species turnover, as some species invade areas occupied by other species. Most of Earth’s land that is not covered by ice or desert is projected to undergo at least a 30 percent change in plant cover – changes that will require humans and animals to adapt and often relocate.
In addition to altering plant communities, the study predicts climate change will disrupt the ecological balance between interdependent and often endangered plant and animal species, reduce biodiversity and adversely affect Earth’s water, energy, carbon and other element cycles…
When faced with climate change, plant species often must “migrate” over multiple generations, as they can only survive, compete and reproduce within the range of climates to which they are evolutionarily and physiologically adapted. While Earth’s plants and animals have evolved to migrate in response to seasonal environmental changes and to even larger transitions, such as the end of the last ice age, they often are not equipped to keep up with the rapidity of modern climate changes that are currently taking place. Human activities, such as agriculture and urbanization, are increasingly destroying Earth’s natural habitats, and frequently block plants and animals from successfully migrating.
RTFA to learn more about how these scientists developed the software and models to produce this analysis. That it all is understandable is another topic. That doesn’t mean it makes sense to screw up the environment, of course.
A new image from NASA’s Wide-field Infrared Survey Explorer shows what looks like a glowing jellyfish floating at the bottom of a dark, speckled sea. In reality, this critter belongs to the cosmos — it’s a dying star surrounded by fluorescing gas and two very unusual rings.
This new gem rivals what may be Hubble’s most famous image, a shot of the Pillars of Creation taken in 1995. The shot above is of a star-forming region in the Carina Nebula. The enormous pillar of gas and dust is 3 light-years tall. The seam in the middle is the result of new stars forming and emitting powerful gas jets that are ripping the pillar apart.
Hubble’s capabilities are all the more impressive considering the rocky start the telescope suffered through when a defect was discovered in its primary mirror after it had been launched and began returning images that weren’t in focus. Scientists and engineers were able to fix the problem, and today Hubble is more capable than ever with its new Wide Field Camera 3, installed last year.

A Nasa satellite designed to uncover hidden cosmic objects has blasted off from California.
The Wide-field Infrared Survey Explorer (WISE) blasted off from Vandenberg Air Force Base on a Delta II rocket just after 1409 GMT…
The probe is expected to uncover objects that have never seen before, including some of the coolest stars and the most luminous galaxies. The $320m mission will do this by scanning the entire sky in infrared light with a sensitivity hundreds of times greater than ever before.
The satellite will also have a role in planetary protection: WISE will be able to detect some of the darkest near-Earth asteroids and comets.
This would help efforts to determine whether any of these objects could strike Earth in the near future…
Wise joins two other infrared missions in space: Nasa’s Spitzer Space Telescope and the European Space Agency’s Herschel Space Observatory.
