Bizarre 'Alien' Asteroid Discovered Orbiting the Wrong Way Near Jupiter
Late last year, our solar system received an unexpected visitor from interstellar space: The asteroid ‘Oumuamua that was discovered suddenly in October and then just as quickly disappeared, passing briefly through our solar system on the way to somewhere else. But now we have a better chance to study a visitor from beyond our solar system.
According to scientists from the Côte d'Azur Observatory and São Paulo State University, there’s at least one interstellar asteroid already here. They found an interstellar asteroid near the planet Jupiter, and unlike ‘Oumuamua, this asteroid is here to stay.
Asteroid 2015 BZ509 was discovered a few years ago by the Pan-STARRS sky survey, the same one that discovered ‘Oumuamua last year. This new asteroid, 2015 BZ509, is a pretty strange one because it orbits in retrograde—in the opposite direction as pretty much everything else in the solar system.

New Earth-Sized Planet Found 11 Light-Years Away Could Support Life
A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO’s unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b.
It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for ESO’s Extremely Large Telescope, which will be able to search for biomarkers in the planet's atmosphere.
With the data from HARPS, the team found that Ross 128 b orbits 20 times closer than the Earth orbits the Sun. Despite this proximity, Ross 128 b receives only 1.38 times more irradiation than the Earth. As a result, Ross 128 b’s equilibrium temperature is estimated to lie between -60 and 20°C, thanks to the cool and faint nature of its small red dwarf host star, which has just over half the surface temperature of the Sun.
Many red dwarf stars, including Proxima Centauri, are subject to flares that occasionally bathe their orbiting planets in deadly ultraviolet and X-ray radiation. However, it seems that Ross 128 is a much quieter star, and so its planets may be the closest known comfortable abode for possible life.
Although it is currently 11 light-years from Earth, Ross 128 is moving towards us and is expected to become our nearest stellar neighbour in just 79 000 years — a blink of the eye in cosmic terms. Ross 128 b will by then take the crown from Proxima b and become the closest exoplanet to Earth!

The nearest single star to the sun apparently hosts a big, icy planet.
Astronomers have found strong evidence of a frigid alien world about 3.2 times more massive than Earth circling Barnard's Star, a dim red dwarf that lies just 6 light-years from the sun. Barnard's Star is our sun's nearest neighbor, apart from the three-star Alpha Centauri system, which is about 4.3 light-years away.
The newly detected world, known as Barnard's Star b, remains a planet candidate for now. But the researchers who spotted it are confident the alien planet will eventually be confirmed.
"After a very careful analysis, we are 99 percent confident that the planet is there," Ignasi Ribas, of the Institute of Space Studies of Catalonia and the Institute of Space Sciences in Spain, said in a statement.
"However, we'll continue to observe this fast-moving star to exclude possible, but improbable, natural variations of the stellar brightness which could masquerade as a planet," added Ribas, the lead author of a new study announcing the detection of Barnard's Star b. That study was published online today (Nov. 14) in the journal Nature.
Barnard's Star b, if confirmed, will not be the nearest exoplanet to Earth. That designation is held by the roughly Earth-size world Proxima b, which orbits Proxima Centauri, one of the Alpha Centauri trio.
NASA's Kepler space telescope showed that small planets are common in the Milky Way galaxy at large. Together, Proxima b and Barnard's Star b strongly suggest that such worlds "are also common in our neighborhood," study co-author Johanna Teske, of the Department of Terrestrial Magnetism at the Carnegie Institution for Science in Washington, D.C., told Space.com. "And that is super-exciting."
A near solar neighbor
Barnard's Star is named after the American astronomer E.E. Barnard, who in 1916 discovered the speediness Ribas mentioned. No other star moves faster across Earth's sky than Barnard's Star, which travels about the width of the full moon every 180 years.
This unparalleled apparent motion is a consequence of the proximity of Barnard's Star and its high (but not record-setting) velocity of 310,000 mph (500,000 km/h) relative to the sun.
And Barnard's Star is getting closer to us every day: In about 10,000 years, the red dwarf will take over the nearest-star mantle from the Alpha Centauri system. At that time, just 3.8 light-years will separate Barnard's Star from the sun.
Barnard's Star is about twice as old as Earth's sun, one-sixth as massive and just 3 percent as luminous. Because Barnard's Star is so dim, its "habitable zone" — the range of distances where liquid water may be possible on a world's surface — lies extremely close-in. Indeed, researchers estimate that zone to be a sliver that lies 0.06 AU to 0.10 AU from the star. (One AU, or astronomical unit, is the Earth-sun distance — about 93 million miles, or 150 million kilometers.)
The habitable-zone concept is a tricky one, of course. Gauging a world's true habitability requires a strong working knowledge of its atmospheric composition and thickness, among other characteristics. And such information is hard to come by for exoplanets.
A long search
Barnard's Star has long been a target of exoplanet hunters, but their searches have always come up empty — until now.
And the new detection wasn't easy: Ribas and his team analyzed huge amounts of data, both archival and newly gathered, before finally digging up Barnard's Star b.
They used the "radial velocity" method, which looks for changes in starlight caused by the gravitational tug of an orbiting planet. Such tugs cause a star to wobble slightly, shifting its light toward red wavelengths at times and toward the blue end of the spectrum at others, as seen from Earth. [7 Ways to Discovery Alien Planets]
"We used observations from seven different instruments, spanning 20 years of measurements, making this one of the largest and most extensive datasets ever used for precise radial-velocity studies," Ribas said in the same statement. "The combination of all data led to a total of 771 measurements — a huge amount of information!"
Never before had the radial velocity method been used to find such a small planet in such a distant orbit, study team members said. (Big, close-in planets tug their host stars more powerfully and therefore cause more dramatic, and more easily detectable, light shifts.)
Those seven instruments were the High Accuracy Radial Velocity Planet Searcher (HARPS), at the European Southern Observatory's (ESO) La Silla Observatory in Chile; the Ultraviolet and Visual Echelle Spectrograph on the Very Large Telescope, at ESO's Paranal Observatory in Chile; HARPS-North, at the Galileo National Telescope in the Canary Islands; the High Resolution Echelle Spectrometer, at the Keck 10-meter telescope in Hawaii; the Carnegie Institute's Planet Finder Spectrograph, at the Magellan 6.5-m telescope at Las Campanas Observatory in Chile; the Automated Planet Finder at the 2.4-m telescope at the University of California's Lick Observatory; and& CARMENES, at the Calar Alto Observatory in Spain.
The researchers also detected hints of another possible planet in the system, orbiting farther out than Barnard's Star b — way farther out, with an orbital period of 6,600 Earth days. But this second signal is too weak to be deemed a planet candidate, Teske said.
"There's not enough data," she told Space.com.
A frigid super-Earth
Barnard's Star b is at least 3.2 times more massive than our own planet, making it a "super-Earth" — the class of worlds that are significantly larger than Earth but smaller than "ice giants" such as Neptune and Uranus.
The newfound planet candidate lies 0.4 AU from its host star and completes one orbit every 233 Earth days, according to the new study.
This orbital distance is similar to that of radiation-blasted Mercury in our own solar system. But, because Barnard's Star is so dim, the potential planet lies right around the system's "snow line" — the region where volatile materials such as water can condense into solid ices.
"Until now, only giant planets had been detected at such a distance from their stars," Rodrigo Diaz, of the Institute of Astronomy and Space Physics at the National Council of Scientific and Technical Research and the University of Buenos Aires in Argentina, said in an accompanying "News and Views" article that was also published today in Nature.
"The authors' discovery of a low-mass planet near the snow line places strong constraints on formation models for this type of planet," added Diaz, who was not involved in the new study.
Barnard's Star b, if it does indeed exist, is not a very promising abode for life as we know it, at least not on the surface. The potential planet is likely very cold, with an estimated surface temperature of about minus 275 degrees Fahrenheit (minus 170 degrees Fahrenheit), study team members said.
Confirmation of Barnard's Star b is unlikely to come from additional radial-velocity measurements, Diaz wrote. But super-precise measurements of star positions, such as those now being made by the European Space Agency's Gaia spacecraft, may do the job in the next few years, he added.
"Even more excitingly, the next generation of ground-based instrumentation, also coming into operation in the 2020s, should be able to directly image the reported planet, and measure its light spectrum," Diaz wrote.
"Using this spectrum, the characteristics of the planet’s atmosphere — such as its winds and rotation rate — could be inferred," he added. "This remarkable planet therefore gives us a key piece in the puzzle of planetary formation and evolution, and might be among the first low-mass exoplanets whose atmospheres are probed in detail."

Journey from Earth to the Edge of the Universe - A Mind-Blowing Trip Through the Cosmos
On a beautiful, clear night, the stars seem so close you could almost reach out and touch them. How far away are the stars? What lies beyond them? How large is the universe as a whole?
Without knowing distances, the sky is just a starry bowl over our heads – like the dome of a planetarium.
If we can figure out the distance to the stars, we will begin to see what the universe looks like in three dimensions, and we will begin to answer some of the greatest of questions: How old is the universe? Is it infinitely large? What is our place in the cosmos?

Massive amounts of data are generated by orbiting scientific platforms like the Hubble, and the ESA’s Gaia satellite; so much data that it often takes years for researchers to pour through. An international team of astronomers were pouring through Gaia data recently and discovered a massive “ghost” galaxy hiding behind the shroud of the Milky Way’s disc. The new galaxy has been named Antila 2 or Ant 2 and is said to be an extremely low-density galaxy.

Greenbelt MD (SPX) Nov 14, 2018
Violent and destructive, active volcanoes ought to be feared and avoided. Yet, these geological cauldrons expose the pulse of many planets and moons, offering clues to how these bodies evolved from chemical soups to the complex systems of gases and rocks we see today.
Unearthing these clues is what motivates planetary scientists from NASA's Goddard Space Flight Center in Greenbelt, Maryland, to venture to inhospitable places on this planet that most people try to avoid: smoldering lava fields and glacier-covered volcanoes.
