New study of 1980s Mars meteorite debunks proof of ancient life on planet

Scientists who were part of original 1996 study stand by their observations claiming new findings are ‘disappointing’A four billion-year-old meteorite from Mars that caused a splash here on Earth decades ago contains no evidence of ancient, primitive Martian life after all, scientists have said.In 1996, a Nasa-led team announced that organic compounds in the rock appeared to have been left by living creatures. Other scientists were skeptical and researchers chipped away at that premise over the ...

Astronomers spotted a distant planet in the middle of making its own moon

The PDS 70 system, located nearly 400 light-years away and still in the process of being formed, with planet PDS 70c circled in blue. ALMA (ESO/NAOJ/NRAO)/Benisty et al. Astronomers have captured a distant planet adorned with a moon-making disc for the first time. The planet has captured enough gas and dust in its orbit to make three moons the size of Earth's. By studying this world and its star, astronomers can learn more about how planets and moons are born. See more stories on Insid...

Beyond Pluto: the hunt for our solar system's new ninth planet

Scientists think a planet larger than Earth lurks in the far reaches of the solar system. Now a new telescope could confirm their belief and change solar system scienceYou’d think that if you found the first evidence that a planet larger than the Earth was lurking unseen in the furthest reaches of our solar system, it would be a big moment. It would make you one of only a small handful of people in all of history to have discovered such a thing.But for astronomer Scott Sheppard of the Carnegie I...

Saturn declared most moonfluential planet after follower count reaches 82

A team of researchers from the Carnegie Institution for Science recently announced the discovery of 20 new planets surrounding Saturn. This moves the ringed planet past Jupiter as the most ‘moonfluential’ denizen of our solar system. The new moons were discovered using the Subaru telescope in Hawaii. After careful observation, the team determined that the new moons were similar in size and, with the exception of three, orbiting the planet backwards. According to a press release from Carnegie: Ea...

Astronomers spot 20 more moons of Saturn — and want you to help name them

Saturn has pulled ahead of Jupiter again in the moon discovery race, thanks to a batch of 20 outer moons that bring the ringed planet's total tally to 82. The newly reported satellites, confirmed by the International Astronomical Union's Minor Planet Center, were found by the same team that reported spotting 12 new moons of Jupiter last year. As was the case with those moons of Jupiter, the discovery team at the Carnegie Institution for Science is soliciting suggestions for naming the ne...

The Day Edwin Hubble Realized Our Universe Was Expanding

This year marks the 90th anniversary of a mind-boggling discovery: that the universe is expanding. The discovery was spearheaded by Edwin Hubble, for whom the orbiting Hubble Space Telescope is named. As an astronomer at Mount Wilson Observatory in Los Angeles, Hubble had access to the most cutting-edge equipment of the day, particularly the 100-inch (2.5 meters) Hooker telescope. The telescope, built in 1917, was the largest on Earth until 1949. Since 1919, Hubble had been discovering new gal...

Astronomers spotted the most distant object in the Solar System, named it ‘Farout’

You've really got to hand it to space scientists. They regularly deliver mind-blowing news that tells us more and more about the universe we live in, and they manage to do it all while keeping a pretty good sense of humor. Take the recent discovery of a new, super-distant Solar System object called 2018 VG18, for example. In a new announcement by the International Astronomical Union's Minor Planet Center, the existence of the object was revealed, along with its very tongue-in-cheek nick...

Solar system's most distant object is 'Farout' pink dwarf planet

Astronomer Scott Sheppard of the Carnegie Institution for Science in Washington said on Tuesday the dwarf planet, officially designated as 2018 VG18, is estimated to have a diameter of 310 to 375 miles (500 to 600 km). There are roughly 50 dwarf planets in the solar system. Its discovery was announced on Monday by the International Astronomical Union's Minor Planet Center.

Farout! Astronomers identify the most distant known object in our solar system

Astronomers say they’ve discovered the most distant body ever observed in our solar system, a potential dwarf planet that’s about 11 billion miles from the sun. Its nickname? “Farout.” The far-out object — which is also known by its more official but less colorful designation, 2018 VG18 — was detected with Japan’s 8-meter Subaru Telescope in Hawaii during a campaign to look for extremely distant solar system objects, including a hypothetical Planet X or Planet Nine. Further observations to confi...

Global warming may be more severe than expected by 2100 - study

World temperatures could rise 15 percent more than expected this century, obliging governments to make deeper cuts in greenhouse gas emissions to limit global warming, scientists said on Wednesday. Average surface temperatures could increase up to 0.5 degree Celsius (0.9 Fahrenheit) more than previously projected by 2100 in the most gloomy scenarios for warming, according to a study based on a review of scientific models of how the climate system works. "Our results suggest that achievi...

Big data points humanity to new minerals, new deposits

Researchers have found a way to predict minerals missing from those known to science, where to find them, and where to look for new deposits of valuable minerals such as gold and copper. In American Mineralogist, Deep Carbon Observatory researchers at the Carnegie Institution for Science report the first application to mineralogy of network theory, best known for analyzing e.g. the spread of disease, terrorist networks, or Facebook connections.

Scientists make huge dataset of nearby stars available to public

Today, a team that includes MIT and is led by the Carnegie Institution for Science has released the largest collection of observations made with a technique called radial velocity, to be used for hunting exoplanets. The huge dataset, taken over two decades by the W.M. Keck Observatory in Hawaii, is now available to the public, along with an open-source software package to process the data and an online tutorial.

Researchers need more proof from Harvard of the claim for the creation of solid metallic hydrogen which is a holy grail of physics

Researchers doubt the Harvard claim that solid metallic hydrogen has been created Ranga Dias and Isaac Silvera, both physicists at Harvard University in Cambridge, Massachusetts, first posted a report of their results on the arXiv preprint server last October, which attracted immediate criticism. A peer-reviewed version of the report was published on 26 January in Science2, but sceptics say that it includes little new information. Silvera and Dias say that they wanted to publish their first obse...

Harvard scientists claim they've made Earth's first metallic hydrogen

For 80 long years, scientists have attempted in vain to produce a metal from hydrogen. A super substance thought to be present on other planets, metallic hydrogen could generate a rocket propellant around four times more powerful than what we possess now, allowing us to make advanced technologies like super-fast computers. Now two scientists at Harvard University say they have achieved the near miraculous. But other scientists are skeptical - the sensational discovery may just be too good to b...

Melting solid below the freezing point

Researchers at the Carnegie Institution for Science have discovered a new phenomenon of so-called metastability in a liquid phase. This state is common in supercooled liquids, which are liquids that cool below the freezing point without turning into a solid or a crystal. These scientists report the first experimental evidence of creating a metastable liquid directly by melting a high-pressure solid crystal of the metal bismuth via a decompression process below its melting point.
