Islamabad: Earth came early to the party in the evolving universe. According to a new theoretical study, when our solar system was born 4.6 billion years ago only eight percent of the potentially habitable planets that will ever form in the universe existed. And, the party won’t be over when the sun burns out in […]

Read MoreCovert Report Islamabad: Humans worry about greenhouse gases, but between 1.8 billion and 800 million years ago, microscopic ocean dwellers really needed them.The sun was 10 to 15 percent dimmer than it is today – too weak to warm the planet on its own. Earth required a potent mix of heat-trapping gases to keep the […]
Read MoreCovert Report Islamabad: About one fifth of Earth’s atmosphere is oxygen, pumped out by green plants as a result of photosynthesis and used by most living things on the planet to keep our metabolisms running.But before the first photosynthesizing organisms appeared about 2.4 billion years ago, the atmosphere likely contained mostly carbon dioxide, as is […]

Once a mere line item on business plans, the coronavirus pandemic has moved digitization from consideration to requirement.While many executives have digitized parts of their business, we’re entering […]
Read MoreNewswire Islamabad: Earth-like planets orbiting close to small stars probably have magnetic fields that protect them from stellar radiation and help maintain surface conditions that could be conducive to life, according to research from astronomers at the University of Washington.A planet’s magnetic field emanates from its core and is thought to deflect the charged particles […]
Read MoreIslamabad: Certain primordial stars – those between 55,000 and 56,000 times the mass of our Sun, or solar masses — may have died unusually. In death, these objects – among the Universe’s first-generation of stars — would have exploded as supernovae and burned completely, leaving no remnant black hole behind. Astrophysicists at the University of […]
Read MoreNewswire Islamabad: Boiling oceans and searing air temperatures will render our planet uninhabitable in the distant future, University of East Anglia scientists claimed.We do at least have time to book our tickets to Mars or any of the other 1,000 “suitable” planets detected so far, according to Andrew Rushby of the University of East Anglia […]
Read MoreIslamabad: For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the first time, researchers using ALMA and a host of other radio telescopes have found direct evidence that merging galaxies can instead form disc galaxies, and that this outcome is in fact quite common. This surprising […]
Read MoreCovert ReportAn international team of astronomers have announced the discovery of a rare molecule — phosphine — in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments.Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes — floating […]
Read MoreIslamabad: Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist if replenished by life. But those gases come from simple life forms like microbes. What about advanced civilizations? Would they leave […]
Read MoreAstronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer to their stars and have much shorter orbital periods. “Finding Kepler-421b was a stroke of […]
Read MoreThe discovery of two new jumbo-sized viruses is blurring the lines between viral and cellular life and could point to the existence of a new type of life, scientists suggest. The two large viruses, detailed in this week’s issue of the journal Science, have been dubbed “Pandoraviruses” because of the surprises they may hold for […]
Read MoreIslamabad: An international group of astronomers has used the ESO 3.6-metre telescope to identify a planet just like Jupiter orbiting at the same distance from a Sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays an important role in shaping the architecture of planetary systems. The existence of a Jupiter-mass […]
Read MoreMcGill Physics student Evelyn Macdonald and her supervisor Prof. Nicolas Cowan used over a decade of observations of Earth’s atmosphere taken by the SCISAT satellite to construct a transit spectrum of Earth, a sort of fingerprint for Earth’s atmosphere in infrared light, which shows the presence of key molecules in the search for habitable worlds.

Read MoreBy Emily Conover Like a metronome that sets the tempo for a musician, a fundamental cosmic clock may be keeping time throughout the universe. But if such a clock exists, it ticks extremely fast. In physics, time is typically thought of as a fourth dimension. But some physicists have speculated that time may be the […]

Read MoreSilverback gorillas appear to use odor as a form of communication to other gorillas, according to a study published in the open-access journal PLOS ONE by Michelle Klailova from University of Stirling, UK, and colleagues. Mammals communicate socially through visual, auditory, and chemical signals. The chemical sense is in fact the oldest sense, shared by […]
Read MoreDefining what makes a star “Sun-like” is as difficult as defining what makes a planet “Earth-like.” A solar twin should have a temperature, mass, and spectral type similar to our Sun. We also would expect it to be about 4.5 billion years old. However, it is notoriously difficult to measure a star’s age so astronomers […]
Read MoreThe Earth’s magnetic field flips, every few hundred thousand years or so on average, which means magnetic north becomes magnetic south and vice versa (the planet doesn’t actually turn upside down). New research suggests this change of direction can happen up to 10 times faster than previously thought. That’s big news for scientists studying how […]
Read MoreScientists have identified the fossilized remains of an extinct giant bird that could be the biggest flying bird ever found. With an estimated 20-24-foot wingspan, the creature surpassed size estimates based on wing bones from the previous record holder — a long-extinct bird named Argentavis magnificens — and was twice as big as the Royal […]

Read MoreSurrounding the sun is a vast atmosphere of solar particles, through which magnetic fields swarm, solar flares erupt, and gigantic columns of material rise, fall and jostle each other around. Now, using NASA’s Solar Terrestrial Relations Observatory, scientists have found that this atmosphere, called the corona, is even larger than thought, extending out some 5 […]
Read MorePlanets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a two-billion-year discrepancy for computer models estimating Saturn’s age. “Models that correctly predict Jupiter to be 4.5 billion years old find Saturn to be only 2.5 billion […]
Read MoreAstronomers using the National Science Foundation’s Green Bank Telescope (GBT) in West Virginia, along with data from other large radio telescopes, have discovered that our nearest galactic neighbors, the dwarf spheroidal galaxies, are devoid of star-forming gas, and that our Milky Way Galaxy is to blame. These new radio observations, which are the highest sensitivity […]
