Direct imaging of exoplanets was once only possible for the brightest of planets orbiting the dimmest of stars — but improving technology is turning this into an increasingly powerful technique. In a new study, direct-imaging observations of the Jupiter-like exoplanet 51 Eridani b provide tantalizing clues about its atmosphere.y & Telescope.

The Earth and Sun, not so different from how they might have appeared 4 billion years ago. Yet daily or even hourly changes can tell us incredible information about near-term environmental and ecological threats to our world. Image credit: NASA / Terry Virts.With the launch of JPSS-1 coming up this year, everything that NASA Earth science stands for hinges on its success.“There is, then, no water that is wholly of the Pacific, or wholly of the Atlantic, or of the Indian or the Antarctic. The surf that we find exhilarating at Virginia Beach or at La Jolla today may have lapped at the base of antarctic icebergs or sparkled in the Mediterranean sun, years ago, before it moved through dark and unseen waterways to the place we find it now. It is by the deep, hidden currents that the oceans are made one.” -Rachel CarsonWhen it comes to viewing anything in space that changes — whether it’s a distant galaxy, star, or even the Sun or Earth in our own backyard — the goal is to measure it as frequently and comprehensively as possible. For the Earth, that means imaging the planet at high resolution, with as many instruments as ...

NASA’s Curiosity rover as seen simultaneously on Mars surface and from orbit on Sol 1717, June 5, 2017. The robot snapped this self portrait mosaic view while approaching Vera Rubin Ridge at the base of Mount Sharp inside Gale Crater – backdropped by distant crater rim. This navcam camera mosaic was stitched from raw images and colorized. Inset shows overhead orbital view of Curiosity amid rocky mountainside terrain taken the same day by NASA’s Mars Reconnaissance Orbiter.

Earlier this month on June 5, researchers commanded NASA’s Mars Reconnaissance Orbiter (MRO) to image the car sized Curiosity rover from Mars orbit using the spacecrafts onboard High Resolution Imaging Science Experiment (HiRISE) telescopic camera during Sol 1717 of her Martian expedition – see below. HiRISE is the most powerful telescope ever sent to Mars. And as she ...

Are astronomers being misled by the quirky alignment of orbits that they’re finding in the distant Kuiper Belt? Even as the count of known planets around other stars continues to climb, a small group of observational astronomers and dynamicists are fixated on something much closer to home: tantalizing clues that a super-Earth-size planet lurks undiscovered somewhere beyond the Kuiper Belt in our own solar system. Some have dubbed it "Planet X," others "Planet Nine," and right now observing teams are using some of the world’s largest telescopes in a race to track it down. One big problem is that they’re not sure where to look — or if it even exists. Orbits for the six most distant known objects in the solar system as of early 2016, whose orbits (shown in magenta) remain beyond Neptune, all align in one direction. A hypothesized massive "Planet Nine" (orange orbit) could be responsible for their perplexing alignment.Caltech / Robert Hurt The evidence so far is purely circumstantial. To recap, observers have started to accumulate discoveries of a class of far-flung objects in a kind of dynamical "no man's land." They have very eccentric orbits that average at least 150 astronomical units from the ...
