New planets outside our solar system! We discovered the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds-all of them with the potential for water on their surface-is an exciting discovery in the search for life on other worlds. The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water - key to life as we know it - under the right atmospheric conditions, but the chances are highest with the three in the habitable zone. This illustrations show planets of the TRAPPIST-1 system, including a travel poster and the possible surface of TRAPPIST-1f, one of the newly discovered planets.

New discovery! Today at 1 p.m. EST, we're presenting new findings on planets that orbit stars other than our sun, known as exoplanets. Here's a collection of some previous exoplanet discoveries. Some of these are rocky, some are gaseous and some are very, very cold. But there's one thing each these strange new worlds have in common: All have advanced scientific understanding of our place in the cosmos. Check out these 9 exoplanets, along with artist's concepts depicting what they might look like...

LIFTOFF! The Falcon 9 rocket lifted off at 9:39 a.m. EST, and the Dragon cargo vehicle is on orbit heading to the International Space Station with an arrival scheduled for Wednesday, Feb. 22. It will deliver science and supplies to the crew living and working on station.

While this lovely image contains hundreds of distant stars and galaxies, one vital thing is missing - the object Hubble was actually studying at the time! This is not because the target has disappeared. The telescope's camera actually uses two detectors: the first captures the object being studied - in this case an open star cluster known as NGC 299 - while the other detector images the patch of space just 'beneath' it. This is what can be seen here. Technically, this picture is merely a sidekick of the actual object of interest - but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own. It may initially seem to show just stars, but a closer look reveals many of these tiny objects to be galaxies. The spiral galaxies have arms curving out from a bright center. The fuzzier, less clearly shaped galaxies might be ellipticals. Some of these galaxies contain millions or even billions of stars, but are so distant that all of their starry residents are contained within just a small pinprick of light that appears to be the same size as a single star! The bright blue dots are very hot stars, sometimes distorted into crosses by the struts supporting Hubble's secondary mirror. The redder dots are cooler stars, possibly in the red giant phase when a dying star cools and expands.

The tenth SpaceX cargo resupply launch to the International Space Station (@ISS), targeted for launch Feb. 18, will deliver SAGE III to measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere. Understanding these measurements will allow national and international leaders to make informed policy decisions regarding the protection and preservation of Earth's ozone layer. Ozone in the atmosphere protects Earth's inhabitants, including humans, plants and animals, from harmful radiation from the sun, which can cause long-term problems such as cataracts, cancer and reduced crop yield. During Expedition 45, ESA astronaut Andreas Mogensen captured pictures of blue jets, elusive electrical discharges in the upper atmosphere, with the most sensitive camera on the orbiting outpost to look for these brief features.

The Andromeda constellation is home to the pictured galaxy. Many different classifications are used to identify galaxies by shape and structure - this one is a barred spiral type. These are recognizable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy's center. There is evidence that this galaxy has experienced some kind of interaction in its past. Galaxies contain vast amounts of mass, and therefore affect one another via gravity. Sometimes these interactions can be mild, and sometimes hugely dramatic, with two or more colliding and merging into a new, bigger galaxy. Understanding the history of a galaxy, and what interactions it has experienced, helps astronomers to improve their understanding of how galaxies - and the stars within them - form.

This artist's concept shows a massive, comet-like object falling toward a white dwarf. New Hubble Space Telescope findings are evidence for a belt of comet-like bodies orbiting the white dwarf, similar to our solar system's Kuiper Belt. The findings also suggest the presence of one or more unseen surviving planets around the white dwarf, which may have perturbed the belt to hurl icy objects into the burned-out star.

Jupiter from below! This enhanced-color image of Jupiter's south pole and its swirling atmosphere was created by citizen scientist Roman Tkachenko using data from the JunoCam imager on our Juno spacecraft. Juno acquired the image, looking directly at the Jovian south pole, on February 2, 2017, at 6:06 a.m. PST (9:06 a.m. EST) from an altitude of about 63,400 miles (102,100 kilometers) above Jupiter's cloud tops. Cyclones swirl around the south pole, and white oval storms can be seen near the limb -- the apparent edge of the planet.

Comet hunters still have a chance to see comet 45P/Honda-Mrkos-Pajdušáková in the next few days using binoculars or a telescope. It's the first of a trio of comets that will -- between now and the end of 2018 -- pass close enough to Earth for backyard observers to try to spot and for scientists to study using ground-based instruments. This image of Comet 45P/Honda-Mrkos-Pajdušáková was captured using a telescope on December 22 from Farm Tivoli in Namibia, Africa.
