    The most distant object humanity has ever visited looks something like a spinning snowman or hourglass that’s lost in space.Researchers who work on NASA’s nuclear-powered New Horizons mission released a movie on Tuesday showing the rotation of the mountain-size rock, which is known formally as (486958) 2014 MU69.(It’s more commonly referred to as “Ultima Thule”.)Mu69 is about 4 billion miles (6 billion kilometres) from Earth and 1 billion miles (2 billion kilometres) beyond Pluto.New Horizons flew by the object on New Year’s Day at a speed of 32,200 miles per hour (52,000 kilometres per hour), and came within about 2,200 miles...
  • The diet to save lives, the planet and feed us all?

    BBC ^ | 1/16/19 | James Gallagher
    A diet has been developed that promises to save lives, feed 10 billion people and all without causing catastrophic damage to the planet. Scientists have been trying to figure out how we are going to feed billions more people in the decades to come. Their answer - "the planetary health diet" - does not completely banish meat and dairy. But it requires a ginormous shift in what we pile onto our plates and turning to foods that we barely eat. What changes am I going to have to make? If you eat meat every day then this is the first...
  • A Diamond the Size of Earth - is this Jupiter's core?

    In his book "2061 - Odyssey Three" (the third of his Space Odyssey series), Arthur C. Clarke put forward the intriguing proposal that the core of the planet Jupiter was, in fact, a diamond the size of Earth. Now Clarke, even though a science fiction author of some repute, had a science background and always tried to bring rigorous scientific accuracy to his stories. So, could his proposition be possible? The somewhat predictable answer is - we don't know. But we can analyse the possibility within known scientific parametres, to see if it is, at least, possible. For diamond to...
  • 'Farout!' Newfound Object Is the Farthest Solar System Body Ever Spotted

    Space.com ^ | December 17, 2018 01:00pm ET | Sarah Lewin,
    The discovery team nicknamed the object "Farout," and its provisional designation from the International Astronomical Union is 2018 VG18. Preliminary research suggests it's a round, pinkish dwarf planet. The same team spotted a faraway dwarf planet nicknamed "The Goblin" in October. The object is more than 3.5 times the current distance between Pluto and the sun (34 AU), and it outpaces the previous farthest-known solar system object, the dwarf planet Eris, which is currently about 96 AU from the sun. NASA's Voyager 2 spacecraft recently entered interstellar space at about 120 AU, leaving the sun's "sphere of influence" called the...

    Astronomers have captured one of the most detailed views of a young star taken to date, and revealed an unexpected companion in orbit around it. While observing the young star, astronomers led by Dr. John Ilee from the University of Leeds discovered it was not in fact one star, but two.The main object, referred to as MM 1a, is a young massive star surrounded by a rotating disc of gas and dust that was the focus of the scientists' original investigation.A faint object, MM 1b, was detected just beyond the disc in orbit around MM 1a. The team believe this...

    About 11 light-years away, Ross 128 b is closer to the solar system than any known exoplanet save Proxima b. First there was Proxima b, the Earth-sized planet orbiting the closest star to us, Proxima Centauri. Then came the seven Earth-sized worlds orbiting TRAPPIST-1, a star 39 light-years away, three of which are in the habitable zone. Now we welcome a new tantalizing exoplanet to the group, the second closest we know of, also Earth-sized and temperate, orbiting a calm red dwarf star: Ross 128 b. Ross 128 is an old, inactive red dwarf star that sits 11 light-years away....

    How do you describe something that is beyond ridiculous, beyond absurd? How do you paint a picture of something that is so upside down that it defies logic and reason? Let me give it my best shot. Not a word here is exaggerated or made-up. In 1997, a woman whom we'll call "Mrs. H." was jogging when a man jumped out of the woods and tried to rape her. She was able to fight him off and ran for her life, bruised and cut on the outside and deeply traumatized on the inside. Police were called; trained dogs searched the...

    A bizarre rogue planet without a star is roaming the Milky Way just 20 light-years from the Sun. And according to a recently published study in The Astrophysical Journal, this strange, nomadic world has an incredibly powerful magnetic field that is some 4 million times stronger than Earth’s. Furthermore, it generates spectacular auroras that would put our own northern lights to shame. The new observations, made with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA), not only are the first radio observations of a planetary-mass object beyond our solar system, but also mark the first time...
  • 'Planet Parade' to light up night sky in March: How to watch the rare event

    Stargazers, get your binoculars ready: a string of bright planets, called a "Planet Parade," will grace the night's sky this week, and the show is expected to last several days. It's just the start of what will be a breathtaking month. A "worm moon" rose on March 1, and another full moon, known as a "blue moon," will pop up on March 31. But this may be the most stunning show yet. A rare parade of planets, including Jupiter, Mars, Saturn, Mercury and Venus along with the bright star Antares, will light the sky starting March 7, though they won't...

    In a clean room inside a clean room at NASA’s Kennedy Space Center, a petite telescope is perched on a stand for a final series of checkouts prior to launch. The extra fastidiousness is because the observatory’s four cameras will fly without protective covers—one of several simplifying design decisions made to help ensure the Transiting Exoplanet Survey Satellite, or TESS, will meet its goal of measuring the masses of at least 50 small, rocky and potentially Earth-like worlds as part of the first all-sky, exoplanet survey. TESS was proposed even before NASA’s planet-hunting Kepler space telescope, launched in 2009, demonstrated...
  • Jupiter’s Great Red Spot may be dying, and could disappear within our lifetimes

    “In truth, the GRS has been shrinking for a long time,” Glenn Orton of NASA’s Jet Propulsion Laboratory told Business Insider. The storm was once as large as four times the diameter of Earth, but more recent observations have shown that it’s rapidly losing steam. “Now it’s something like 13 degrees wide in longitude and only 1.3 times the size of the Earth,” Orton says. “Nothing lasts forever.” Late last year, Juno revealed some surprising information about the huge storm, including how deep into the planet it goes. The data showed that the storm is up to 100 times deeper...

    Like Jupiter, Neptune has a giant spinning mystery. NASA's Hubble Telescope captured a time-lapse of the storm for the first time and found a surprising conclusion—it is shrinking. Officially called a "dark vortex," the Neptunian storm shares a few properties with Jupiter's Great Red Spot (GRS). Like the GRS, a dark vortex is moving in a anti-cyclonic direction that sweeps up material from the planet's icy atmosphere. “We have no evidence of how these vortices are formed or how fast they rotate,” said Agustín Sánchez-Lavega from the University of the Basque Country in Spain in a NASA press statement. “It...

    Astronomers have found a cool, Earth-sized planet that's relatively close to our Solar System. The properties of this newly discovered planet - called Ross 128 b - make it a prime target in the search for life elsewhere in the cosmos. At just 11 light-years away, it's the second closest exoplanet of its kind to Earth. But the closest one, known as Proxima b, looks to be less hospitable for life. Found in 2016, it orbits the star Proxima Centauri, which is known to be a rather active "red dwarf" star. This means that powerful eruptions of charged particles periodically...

    Jupiter and Venus will pair up in the sky on Monday morning, shining brightly together shortly before sunrise. The two planets will appear so close together that they may look like they are just one bright star rather than two planets. This is the closest these two planets will appear all year, an astronomical event known as a conjunction. Venus and Jupiter may appear very close to each other in the morning sky, but they are actually more than 400 million miles away from each other. Venus and Jupiter will rise together about one hour before sunrise in the eastern...

    Regardless of your worldview, people are experiencing a quickening in their spirit with the anticipation that world-changing events are just over the horizon. Geopolitical, Social and Spiritual conflicts are heating up all over the globe at an unprecedented and frenzied pace to the point where even the discerning Christian may have trouble keeping track of this whirlwind of event. Luckily, there are still a few messengers, crying out in the wilderness of biblical babble that is permeating the collective conscience of our nation and world, warning believers and unbelievers alike of the signs that are converging toward the soon return...

    Arnold Schwarzenegger has four Hummers and likes nothing better than getting up at 5am to ride his Harley Davidson to the beach for breakfast. Yet "The Terminator" star insists that should not stop him being an environmental evangelist. "Saving the planet is also about technology," the former California governor told AFP, putting his foot on a chair and wagging a skull-ringed finger to make his point. Three of his Hummers run on hydrogen, vegetable oil and bio-diesel and he's hoping to put an electric engine into the fourth. "You know one day soon we are going to have hydrogen-fuelled planes....

    Planetary Discovery around Ultracool Starby Paul Gilster on April 28, 2017 I have a special enthusiasm for microlensing as a means of exoplanet discovery. With microlensing, you never know what you’re going to come up with. Transits are easier to detect when the planet is close to its star, and hence transits more frequently. Radial velocity likewise sends its loudest signal when a planet is large and close. Microlensing, detecting the ‘bending’ of light from a background object as it is affected by a nearer star’s gravitational field, can turn up a planet whether near to its star or far,...

    Worship and Service of Creation It is easy to read what Paul says in Romans 1:25—“they exchanged the truth about God for the lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen,” in a purely negative light as describing the very basis of paganism and the worst form of idolatrous narcissism. However, we cannot deny the seductive beauty and power of such a creation. A new study has found that merely watching nature documentaries boosts people’s emotions of awe, contentedness, joy and amusement. By the same token, such activity reduces “feelings of nervousness,...

    August 24, 2006 was a dark day for Pluto enthusiasts. It was on that day that the International Astronomical Union established three conditions a celestial body must meet in order to be considered a planet. A planet must orbit around the sun, it must be massive enough to be rounded by its own gravity, and it must have “cleared the neighborhood” around its orbit, which means, simply put, that it must have a certain amount of gravitational pull. Pluto does not meet the third condition, so once those rules were put in place, Pluto was demoted to “dwarf planet,” 75...
