Stunning new video reveals Solar Orbiter's view of Earth, Mars, and Venus. For nearly a year, a small spacecraft has been making its way toward the Sun in order to capture the closest images of our host star ever taken.
On its way to the Sun, the Solar Orbiter turned back to marvel at the beauty of three Solar System planets as they twinkled in the dark depths of space. A new video reveals the spacecraft's view of Earth, Venus and Mars, capturing the three planets in the midst of their orbit around the Sun.

But among those car brands racing to reach this total valuation, some are closer to the finish line than others. This visualization uses data from Yahoo Finance to rank the world’s top car manufacturers by market capitalization. What could this spell for the future of the automotive industry? Through the eyes of a robot, scientists see an asteroid in unprecedented detail. On February 21, 2019, Japanese astronomers performed a theft that made history.
A Japanese spacecraft touched down on asteroid Ryugu, quickly snatched a piece of the space rock and fled the scene. The act was caught on camera, and in May of this year, scientists from the Japan Aerospace Exploration Agency released the footage, giving us our first up-close-and-personal encounter with the surface of an asteroid. As the year comes to a close, researchers around the world are starting to look forward to getting even closer — by analyzing the sample itself. The video is one of the treasures gathered by Japan's asteroid-sampling spacecraft, Hayabusa2, which spent a long, five-year journey in space before landing on Ryugu.
The solar minimum: A reasonable explanation based on science (not hysteria) The Sun is a busy star.
This fiery ball of hot gas goes through periods of violent eruptions and magnetic explosions that send flashes of radiation into space. But every now and then, even the Sun needs to chill. Our host star is currently in its downtime mode, a period known as solar minimum. However, this current lack of activity from the Sun has some worried that it will lead to a dark, cold summer with possible famine, war — and even volcanoes. So, what exactly is a solar minimum?

Something Weird Is Going on With New Horizons' Next Target. Early Returns from Bennu. The science return from OSIRIS-REx has been surprisingly swift as the spacecraft returns data on near-Earth asteroid 101955 Bennu.
We’re aided here by the timing, as early results are being discussed at the ongoing conference of the American Geophysical Union (AGU) in Washington, DC. The imagery we’ve received of Bennu’s surface has scientists buzzing. Thus Humberto Campins (University of Central Florida) a member of the OSIRIS-REx Science Team, who notes the comparison between what we see now and the Arecibo radar imagery in the late 1990s: “The images are spectacular and spot on, what we expected thanks to predictions made with the instrumentation at the Arecibo Observatory in the late 90s and early 2000s. We will spend a year and a half mapping Bennu and have to wait until mid 2020 [when] we collect the sample, but it is pretty amazing to actually see it now. 6 Strange Facts about the Interstellar Visitor 'Oumuamua. On October 19, 2017, the first interstellar object, ‘Oumuamua, was discovered by the Pan-STARRS survey.
The experience was similar to having a surprise guest for dinner show up from another country. By examining this guest, we can learn about the culture of that country without the need to travel there—a good thing in this case, given that it would take us a hundred thousand years to visit even the nearest star using conventional chemical rockets. Surprisingly, our first interstellar guest appeared to be weird and unlike anything we have seen before. By the time we realized it, the guest was already out the door with its image fading into the dark street, so we did not have a chance to get a second look at its mysterious qualities.
Below is a list of six peculiarities exhibited by ‘Oumuamua: Something Violent Happened to Our Solar System's First Interstellar Visitor. An interstellar object called 'Oumuamua has confounded astronomers ever since it passed through our solar system in October of last year.
Scientists initially thought that the object — the first-ever visitor from another solar system spotted by Earth-based telescopes — was a comet. Later, they considered it an asteroid and even later described it as a possibly comet-like icy body with a rocky crust. Now, scientists have found that in addition to its confusing appearance, 'Oumuamua — an up to 1,300-foot-long (400 meters), cucumber-shaped object — likely has a rather dramatic history. [Danger! The sun has gone wrong and scientists don’t know why. This article was originally published on The Conversation.

These massive sunspots are regions of intense and complicated magnetic fields that can produce solar flares—bursts of high-energy radiation. You can just make them out with solar viewing glasses, but they’re better viewed through a solar telescope. These two huge sunspots are currently causing quite a bit of consternation and interest. Keep up with this story and more by subscribing now The sun goes through 11-year cycles of solar activity. We’re heading into the bottom of solar minimum, when the sun tends to have fewer sunspots, solar flares and coronal mass ejections—large expulsions of plasma, electrons and ions, and magnetic fields.

A giant planet that orbits close to its sun is called a ‘hot Jupiter.’
Such a planet can have many layers in its atmosphere. (Illustration: NASA/ESA/G. Bacon (STScI)) NASA Spacecraft Gets Up Close With Jupiter's Great Red Spot. Artist's impression of Jupiter's Great Red Spot heating the upper atmosphere.

Jupiter Is Much Stranger Than Scientists Thought - The Atlantic. About every eight weeks, hundreds of millions of miles away, a basketball court-sized spacecraft named Juno swoops toward Jupiter. For a few hours, Juno loops around the planet’s poles at high speed, sometimes getting within 2,100 miles of its atmosphere. It surveys Jupiter’s swirling, opaque cloud tops, and then gets flung out to the other edge of its orbit, beyond Callisto, the planet’s cratered moon.
Jupiter is surrounded by a massive magnetic field that produces belts of radiation capable of frying Juno if it wasn’t wearing 400 pounds of protective titanium. The poles are a haven from the strongest radiation, and it’s there that Juno can aim its various scientific instruments at Jupiter’s cloud cover and collect data. NASA to Explore an Asteroid Containing Enough Mineral Wealth to Collapse the World Economy. We think of asteroids as giant useless rocks floating around space. Perhaps it’s a good place to hide the Millennium Falcon or a worrisome cause of a cataclysmic event. Though most are hunks of rock or ice, some are replete with iron, platinum, gold, and other precious minerals. Two NASA missions plan to explore such an asteroid, scheduled for 2021 and 2023.
See What the Huygens Spacecraft Saw When it Landed on Titan. ESA/NASA/JPL/University of Arizona Perhaps the most exciting part of the Cassini spacecraft's 12-and-a-half years orbiting Saturn was back in December 2004, when the mothership deposited the European Space Agency's Huygens probe. Twenty days later, in January 2005, Huygens became the first spacecraft to land on an object in the outer solar system. Scientists Find Hints Of A Giant, Hidden Planet In Our Solar System.

Caltech/R. Hurt (IPAC) hide caption. Rosetta discovers active sinkholes on 67P. The Rosetta spacecraft appears to have discovered the presence of a series of sinkholes on the surface of comet 67P/Churyumov–Gerasimenko (67P). They're responsible for some of the increasingly active gas streams that are being observed by the orbiter as the comet speeds towards perihelion. The new discovery was made using Rosetta's OSIRIS camera at a distance of 10 - 30 km (6 - 19 miles) between August - October 2014. In all, 18 of the pits were discovered pockmarking the irregular northern hemisphere of 67P. The pits vary in size between a few tens of meters to hundreds of meters in diameter, with some extending 210 m (689 ft) below the comet's surface. The scientists who made the discovery note that the internal features of the walls vary greatly from pit to pit, and that a concentration of the sinkholes on one area of the comet compared to another could hint at an uneven distribution of ice on 67P.

Not very nice, says ESA, whose Rosetta space probe has discovered that comet 67P/Churyumov–Gerasimenko (67P/C-G) has the aroma of rotten eggs and horse dung. View all. A Mysterious Shape Just Appeared on the Surface of Titan. Saturn's moon Titan is sort of like a bizarro version of Earth, an extraterrestrial tease that's home to lakes, rivers, rain, and wind.
This combination of attributes means the would-be twin is host to a variety of landforms Earthlings might find familiar, including mountains and dunes rippling along the solid surfaces of a relatively smooth (uncratered) sphere. Titan is home to the only thick atmosphere so far observed on a natural satellite, along with the only stable surface bodies of liquid (lakes) observed on any celestial body outside of Earth itself. No matter that Titan's rivers and lakes are actually full of liquid methane and ethane and its surface temperature hovers around −179.2 °C, the moon is a playground for the Earth-bound imagination. It helps that Titan also seems interested in playing along. All of those explanations, however, would seem to be things we might have observed previously. Planet Mercury Fully Mapped for First Time.
