Quantum Equation Suggests the Big Bang Never Occurred and the Universe Has No Beginning · The Mind Unleashed. New study gives an astonishing answer to the eternal question of how the world began.
Two astrophysicists argue that the Big Bang may never have happened, meaning the universe may have existed forever. The model they suggest complements Einstein’s theory of general relativity with quantum corrections, and could also explain dark matter and dark energy. This newly discovered icy world could be the key to finding Planet Nine. Scientists have announced the discovery of a new icy world on the fringes of the Solar System, and while this distant object is only very small, it could help us track down something that's meant to be much, much bigger: the hypothesised but as yet unconfirmed Planet Nine.
The new discovery – called L91 – is what's known as a Trans-Neptunian Object (TNO), meaning it's a small world that orbits the Sun beyond Neptune. And that extreme distance means it takes L91 an awfully long time to make its way around the Solar System. Neptune is the most remote confirmed planet in our Solar System, orbiting the Sun at a distance of about 4.5 billion kilometres (2.8 billion miles). In scientific terms, that's around 30 astronomical units (AUs) – meaning 30 times the distance between Earth and the Sun. This newly discovered star system just broke the luminosity record.
Astronomers have spotted a spectacular gamma-ray binary system in a galaxy right next door to our own, and not only is it the first to be found outside the Milky Way - it's also the brightest one yet.
Gamma-ray binaries are systems with two stars: a star like our own Sun, coupled with either a black hole or a small, dense neutron star. These black holes or neutron stars radiate gamma rays - the highest-energy form of light - and this newly discovered system breaks existing luminosity records. NASA to Launch $1.25 Billion Asteroid Redirect Mission (ARM) in 2021. Sep 21, 2016 05:57 AM EDT Asteroids pose a constant threat to Earth and mankind, but these ferocious space rocks can also provide a ton of information about the origin and formation of the Solar System and the universe.
This is the reason why NASA and private companies are interested in gathering more information on asteroids. NASA is planning on launching an Asteroid Redirect Mission (ARM) in 2021, just a few years after the llaunch of asteroid-mapping mission OSIRIS-REx. The OSIRIS-REx mission was launched to space this month to perform surface mapping of asteroid Bennu. The mission is also tasked to collect asteroid samples using its robotic arm and to bring the samples back to Earth for analysis. Since the first asteroid mission is purely scientific in nature, NASA ARM mission will be focused on protecting the Earth from an asteroid collision. Astronomers just spotted deep-space galaxies that are like nothing we've seen before. Astronomers have gazed deep into a distant region of space and found evidence of a hidden trove of young galaxies that are completely unknown to science.
The new observations, made using the Atacama Large Millimetre/submillimetre Array (ALMA) in Chile, give us a whole new perspective on the galactic population of a famous region of space called the Hubble Ultra-Deep Field (HUDF). Back in 2004, scientists stunned the world with the HUDF: an image showing a window of space in the Fornax constellation, depicting some 10,000 galaxies as they existed around 13 billion years ago – only shortly after the Big Bang. At the time, this was the deepest, most revealing gaze into the early Universe that humanity had ever witnessed. And now, several groups of astronomers from around the world have combined their efforts to re-examine this ancient galactic neighbourhood, and discovered the existence of a swathe of baby galaxies within the HUDF that were invisible to the Hubble Space Telescope.
B. NASA can't explain the 'impossible' cloud that's been spotted over Titan. NASA’s Cassini spacecraft just spotted a mysterious ice cloud over Saturn’s largest moon, Titan, and its appearance challenges everything we thought we knew about the moon’s atmosphere.
The Sun will destroy Earth sooner than you might think. There are plenty of ways Earth could go.
It could smash into another planet, be swallowed by a black hole, or get pummelled to death by asteroids. There’s really no way to tell which doomsday scenario will be the cause of our planet’s demise. But one thing is for sure — even if Earth spends the rest of its eons escaping alien attacks, dodging space rocks, and avoiding a nuclear apocalypse, there will come a day when our own sun will eventually destroy us.
This process won’t be pretty, as Business Insider’s video team recently illustrated when they took a look at what will happen to Earth when the sun finally does die out in a blaze of glory. NASA's making a major Kepler announcement tomorrow! Get the popcorn ready.
NASA will host a news teleconference at 1 pm EDT Tuesday, May 10 (5pm UTC, 3am AEST on Wednesday), to announce the latest discoveries made by its planet-hunting mission, the Kepler Space Telescope. Back in March 2009, when Kepler was launched, scientists didn’t know how common planets were outside our solar system. But soon, the telescope revealed that almost all stars host a plethora of alien worlds. Then, in 2014, the spacecraft began a new, extended mission called K2. During its prime mission alone, Kepler discovered: 4,696 candidate exoplanets1,041 confirmed exoplanets12 confirmed exoplanets roughly Earth-sized in the habitable zone of their stars Indeed, because of data brought back from these missions, astronomers believe there may be at least one planet orbiting every star in the sky.
New study shows how rapidly Earth's magnetic field is changing. New research has shown in the most detail yet how rapidly Earth's magnetic field - which acts like a shield to protect us from harsh solar winds and cosmic radiation - is changing, getting weaker over some parts of the world, and strengthening over others.
Although invisible, these changes can have big impacts - the fluctuation is already shifting the location of the magnetic North Pole, and could determine how space events such as solar storms affect us in the future. But thanks to the new study, scientists now think they know what's causing them, and how to predict them going forward. This isn't the first research to show that Earth's magnetic field is changing. Gizmodo. What Is the Limit to How Far We Can Travel in Space? Einstein's Theory of Relativity Holds True for Early Universe, 3D Map Confirms. Just over one hundred years after Albert Einstein proposed his general theory of relativity, scientists have mapped nearly 3,000 ancient galaxies to confirm its rules held true in the early universe.
The galaxies in question, which are 13 billion light-years from Earth, formed less than a billion years after the Big Bang. Researchers created a 3D map of the galaxies' positions to confirm that the effects of relativity are consistent through the life of the universe, suggesting that dark energy plays a role in the universe's expansion. Using the National Astronomical Observatory of Japan's Subaru telescope in Hawaii, researchers measured how the faraway galaxies clustered together and how quickly they moved through space.
Shooting stars show Earth had oxygen eons before we thought. Andrew Tomkins By Jeff Hecht Few things seem more ephemeral than shooting stars streaking across the sky. Did Black Hole “Mimickers” Produce LIGO Signal? Recently detected gravitational waves might not be a signature of black holes but of other massive objects that lack an event horizon. V. Cardoso et al., Phys. Rev. Lett. (2016) A binary star is flying out of our galaxy and researchers don't know why. You don’t need a Stephen Hawking-level of understanding to know that things usually orbit other things in the Universe, but apparently nobody told that to PB 3877 - a binary star system that’s traveling 2 million kilometres per hour (1.24 million mph) away from the Milky Way. Yup, PB 3877 is trying to strike out on its own despite the gravitational pull of our galaxy, and researchers have no idea why.
Even crazier, at such speeds, the binary system may actually reach galactic escape velocity, which would send it into intergalactic space. According to a team of astrophysicists from the University of Erlangen-Nuremberg in Germany, our current understanding of physics cannot explain why PB 3877 is moving in such a manner. These 3 nearby planets could be our best shot yet to find alien life. An international team of astronomers has discovered three Earth-sized exoplanets, all orbiting the same star just 40 light-years from us, the 16-nation intergovernmental research organisation ESO reported on Monday. The scientists have deemed all three planets potentially habitable, an exciting turn in the hunt for 'exoplanets', a term for planets that orbit a star other than our Sun.
And it could bring us closer to finding extraterrestrial life. Astronomers have discovered the first ever comet without a tail. A strange, rocky comet with no tail has been spotted zipping into our inner Solar System, and it's so unique, it's got scientists ready to rewrite the definition of what these ubiquitous cosmic bodies should look like. According to a new report, the comet is carrying up to 1 million times less water than any other comet ever recorded, and it's made up of solid rock, like an asteroid, rather than ice, like a typical comet. So basically what we have here is a cross between an asteroid and a comet, and astronomers are flipping out. Astronomers might have finally detected where mysterious, extragalactic neutrinos are coming from.
Just over three years ago, physicists working in Antarctica announced they'd detected the first evidence of mysterious subatomic particles, known as neutrinos, coming from outside our galaxy. To Scale: The Solar System. To Scale: The Solar System From To Scale: - Path - Curiosity. Mysterious blue flashes in space and upside-down lightning have been caught on film. Strange footage captured by Danish astronaut Andreas Mogensen while on board the International Space Station has revealed unexplained blue 'blobs', and extensive flashes of light piercing the dark expanse of space, while new images of bizarre upside-down lightning have been captured from the ground.
Presented at the European Geosciences Union meeting in Vienna last week, the incredible shots showcase the dynamic light show that occurs above a thunderstorm on Earth - elements of which no one has ever seen before. Filmed from the cupola window of the International Space Station in 2015 during violent thunderstorms over India, Mexico, Thailand, and Costa Rica, the footage features rare columns of electrical discharge called blue jets that can fan up and out as far as 12 kilometres. Astronomers have discovered a region in space where black holes have mysteriously aligned.
