    A mini planetary parade will see Jupiter, Mercury, Uranus, Mars, Neptune and Saturn align above the horizon Astronomy enthusiasts are in for a celestial treat at dawn tomorrow, as a stunning mini planetary parade is set to grace our skies. The early hours of the morning will witness Jupiter, Mercury, Uranus, Mars, Neptune and Saturn aligning just above the horizon. The prospects of catching Uranus with the naked eye might be slim, but it's anticipated that avid sky-gazers across Britain could capture glances of other planets, with some spotted even without the need for binoculars. Shedding light on this space...

    All four of the sun’s giant planets emit more energy than they receive from the sun. Like the sun’s other giant worlds, Uranus (seen in this 1986 photo from the Voyager 2 spacecraft) radiates more energy than the sun gives it, though not nearly as strongly as its massive peers do. JPL/NASA ===================================================================== Uranus emits more energy than it gets from the sun, two new studies report — a discovery that contradicts findings from the venerable Voyager spacecraft. When Voyager 2 sped past Uranus on January 24, 1986, the spacecraft detected no significant excess heat from the planet, making it...

    Research led by Burkhard Militzer, University of California Berkeley This false color photograph of Neptune was made from Voyager 2 images taken through three filters: blue, green, and a filter that passes light at a wavelength that is absorbed by methane gas. (Credit: NASA/JPL) In a nutshell Uranus and Neptune have weird, disorganized magnetic fields because their interiors naturally separate into two distinct layers—a flowing water-rich upper layer and a stable hydrocarbon-rich lower layer. Using advanced simulations of 540 atoms under extreme pressure and temperature, Berkeley physicist Burkhard Militzer discovered that planetary ices (water, methane, and ammonia) spontaneously separate rather...

    The best chance to see as many planets as possible will be just after sunset on Tuesday, Wednesday, Thursday and Friday. Four of the planets - Mercury, Venus, Jupiter, and Mars - will be visible to the naked eye. Saturn will be harder to see because it will be low in the horizon. You will need a telescope to spot the other two planets - Uranus and Neptune. A good view of the horizon and clear skies will offer the best chance of spotting them all. However, the window to see all seven planets will be very brief. Dr Edward...

    An exploded view of an ice giant planet such as Uranus or Neptune. A new theory proposes that below the dense atmosphere lies a water-rich layer (blue) that has separated from a deeper layer of hot, high-pressure carbon, nitrogen and hydrogen (amber). The pressure squeezes hydrogen out of methane and ammonia molecules, creating stratified hydrocarbon layers that cannot mix with the water layer, which prevents the convection that creates a dipolar magnetic field. Credit: Quanta magazine ============================================================================= New research at UC Berkeley offers a fresh perspective on Uranus and Neptune’s interiors, indicating layered structures of water and hydrocarbons. These findings...

    The peculiar layers could explain the ice giants' magnetic peculiarities. Uranus (left) and Neptune (right) are the ice blue giants in the outer Solar System. Image credit: Patrick Irwin/University of Oxford/NASA Uranus and Neptune were only visited once by human spacecraft when Voyager 2 passed by them almost 40 years ago. During those visits, scientists measured peculiar magnetic fields unlike those seen around other planets. A recent paper suggests that the Uranus measurements might have been messed up by the Sun, but in general, it has been difficult to explain the behavior. New research suggests that the magnetic weirdness might...

    New measurements of Neptune's atmosphere by a European space telescope suggest that a comet may have crashed into the gas giant about 200 years ago.Scientists analyzed the composition of Neptune's atmosphere using data from the Herschel space observatory. They found a peculiar distribution of carbon monoxide in the gas giant's atmosphere, which could be an indication of an earlier comet impact...Other similar collisions between comets (or asteroids) and planets helped the astronomers detect the telltale signs of cometary impacts.When pieces of the comet Shoemaker-Levy 9 slammed into Jupiter in 1994, scientists were able to examine the trajectory and debris to...

    Explanation: Ringed ice giant Neptune lies near the center of this sharp near-infrared image from the James Webb Space Telescope. The dim and distant world is the farthest planet from the Sun, about 30 times farther away than planet Earth. But in the stunning Webb view, the planet's dark and ghostly appearance is due to atmospheric methane that absorbs infrared light. High altitude clouds that reach above most of Neptune's absorbing methane easily stand out in the image though. Coated with frozen nitrogen, Neptune's largest moon Triton is brighter than Neptune in reflected sunlight, seen at the upper left sporting...

    Our ideas of the colours of the planets Neptune and Uranus have been wrong, research led by UK astronomers reveals. Images from a space mission in the 1980s showed Neptune to be a rich blue and Uranus green. But a study has discovered that the two ice giant planets are both similar shades of greenish blue. It has emerged that the earlier images of Neptune had been enhanced to show details of the planet's atmosphere, which altered its true colour.

    Sorry, Jupiter. Astronomers have discovered 62 new moons orbiting the ringed planet Saturn. The satellite haul brings the planet's total number of moons to over 100 and also means the gas giant takes back the crown as the solar system's "moon king" from Jupiter. Prior to this discovery, Saturn had 83 moons recognized by the International Astronomical Union(opens in new tab), so the new batch brings the total number to an incredible 145. The discovery marks another milestone for Saturn, with the planet becoming the first world in the cosmos known to be orbited by more than 100 moons. The...

    Quaoar is one of the so-called trans-Neptunian objects, small planets orbiting beyond the solar system's outermost planet Neptune. Quaoar is a proud owner of its own moon, the 100-mile-wide Weywot. And a recent observation campaign revealed that it also has a ring of material in its orbit. Quaoar's ring is at a very unusual distance from its parent body. In fact, before astronomers discovered Quaoar's ring in observations from several telescopes conducted between 2018 and 2021, they had thought that it was impossible for a ring to exist at such a distance. With a radius of about 2,420 miles from...

    University of Arizona scientists have uncovered a curious case of missing asteroids. The main asteroid belt is a zone containing millions of rocky objects between the orbits of Mars and Jupiter. The scientists find that there ought to be more asteroids there than researchers observe. The missing asteroids may be evidence of an event that took place about 4 billion years ago, when the solar system's giant planets migrated to their present locations. UA planetary sciences graduate student David A. Minton and UA planetary sciences professor Renu Malhotra say missing asteroids is an important piece of evidence to support an...

    This is an artist's concept of a hypothetical 10-million-year-old star system. The bright blur at the center is a star much like our sun. The other orb in the image is a gas-giant planet like Jupiter. Wisps of white throughout the image represent traces of gas. Astronomers using NASA's Spitzer Space Telescope have found evidence showing that gas-giant planets either form within the first 10 million years of a sun-like star's life, or not at all. The lifespan for sun-like stars is about 10 billion years. The scientists came to this conclusion after searching for traces of gas around...
  • 'Jupiter swallowed planet 10 times the size of Earth'

    Jupiter, the biggest planet in the solar system, might have gained its dominant position after swallowing up a smaller planet, scientists believe. Studies on Jupiter have revealed that the giant planet, which is more than 120 times bigger than the Earth, has an extremely small core that weighs just two to 10 Earth masses. Now scientists have claimed that Jupiter's core might have been vaporised in huge collision with a planet up to ten times the size of Earth, the New Scientist reported. Researchers led by by Shu Lin Li of Peking University in China have modelled what might have...

    an image of uranus taken using the keck observatory. The planet appears to glow blue against the darkness, with thin, gossamer rings wrapped vertically around its middle Uranus as imaged by the Keck Observatory. (Lawrence Sromovsky, University of Wisconsin-Madison/W.W. Keck Observatory) Uranus marches to the beat of its own weird little drum. Although it shares many similarities with our Solar System's other ice giant, Neptune, it has a bunch of quirks that are all its own. And one of these is impossible to miss: Its rotational axis is so skewed it may as well be lying down. That's a whopping...
