Hubble sees Neptune's mysterious shrinking storm

Thu, 15 Feb 18 00:06:20 -0800

Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm - once big enough to stretch across the Atlantic Ocean from Boston to Portugal - is shrinking out of existence as seen in pictures of Neptune taken by NASA's Hubble Space Telescope.

Are you rocky or are you gassy?

Thu, 08 Feb 18 00:09:20 -0800

A star about 100 light years away in the Pisces constellation, GJ 9827, hosts what may be one of the most massive and dense super-Earth planets detected to date according to new research led by Carnegie's Johanna Teske. This new information provides evidence to help astronomers better understand the process by which such planets form.

IU astronomer helps discover that a star in the constellation Pisces is 'eating' planets

Thu, 21 Dec 17 00:09:00 -0800

An Indiana University astronomer and colleagues have discovered that a distant star called RZ Picseum in the constellation Pisces is crushing one or more planets into its orbit into a vast cloud of gas and dust.

Two Super-Earths around red dwarf K2-18

Tue, 05 Dec 17 00:09:10 -0800

New research using data collected by the European Southern Observatory (ESO) has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the planet has a neighbor.

Pluto's hydrocarbon haze keeps dwarf planet colder than expected

Wed, 15 Nov 17 00:10:30 -0800

The gas composition of a planet's atmosphere generally determines how much heat gets trapped in the atmosphere. For the dwarf planet Pluto, however, the predicted temperature based on the composition of its atmosphere was much higher than actual measurements taken by NASA's New Horizons spacecraft in 2015. A new study published November 16 in Nature proposes a novel cooling mechanism controlled by haze particles to account for Pluto's frigid atmosphere.

NASA investigates invisible magnetic bubbles in outer solar system

Wed, 01 Nov 17 00:08:40 -0700

Forty years ago, the twin Voyagers spacecraft were launched to explore the frontiers of our solar system, and have since made countless discoveries, including finding magnetic bubbles around two of the outer planets.

The return of the comet-like exoplanet

Thu, 14 Sep 17 00:08:40 -0700

Astronomers from UNIGE), also members of the PlanetS, focused the Hubble Space Telescope on an exoplanet that had already been seen losing its atmosphere, which forms an enormous cloud of hydrogen, giving the planet the appearance of a giant comet. During earlier observations, it was not possible to cover the whole cloud, whose shape was predicted by numerical simulations. Thanks to these new observations, the scientists have finally been able to confirm the initial predictions.

Are we being watched? Tens of other worlds could spot the Earth

Fri, 08 Sep 17 00:13:10 -0700

A group of scientists from Queen's University Belfast and the Max Planck Institute for Solar System Research in Germany have turned exoplanet-hunting on its head, in a study that instead looks at how an alien observer might be able to detect Earth using our own methods. They find that at least nine exoplanets are ideally placed to observe transits of Earth, in a new work published in the journal Monthly Notices of the Royal Astronomical Society.

Oil and water may combine if conditions are right, study suggests

Mon, 28 Aug 17 00:16:00 -0700

They say that oil and water do not mix...but now scientists have discovered that -- under certain circumstances -- it may be possible.

Scientists create 'diamond rain' that forms in the interior of icy giant planets

Mon, 21 Aug 17 00:04:20 -0700

In an experiment designed to mimic the conditions deep inside the icy giant planets of our solar system, scientists were able to observe 'diamond rain' for the first time as it formed in high-pressure conditions. Extremely high pressure squeezes hydrogen and carbon found in the interior of these planets to form solid diamonds that sink slowly down further into the interior.

In Neptune, it's raining diamonds

Mon, 21 Aug 17 00:03:00 -0700

Researchers at HZDR have managed to demonstrate 'diamond showers' forming in the ice giants of our solar system. Using the ultra-strong X-ray laser and other facilities at the Stanford Linear Accelerator Center, they simulated the conditions inside the cosmic giants. For the first time ever, they were able to observe the fission of hydrocarbon and the conversion of carbon into diamonds in real time. They published their results in the journal Nature Astronomy.

Scientists probe Neptune's depths to reveal secrets of icy planets

Fri, 11 Aug 17 00:03:20 -0700

Scientists have helped solve the mystery of what lies beneath the surface of Neptune -- the most distant planet in our solar system.

Cretaceous snails conceal themselves in monuments in Madrid

Thu, 03 Aug 17 00:02:50 -0700

The fountains standing next to the Museo del Prado are built using a sedimentary rock full of gastropod shells from the time of the dinosaurs. These fossils have revealed the origin of the stone: forgotten quarries in Redueña, in the province of Madrid, where the building material for the Fountain of Apollo and the Palacio de las Cortes also came from.

Twilight observations reveal huge storm on Neptune

Thu, 03 Aug 17 00:01:00 -0700

Striking images of a storm system nearly the size of Earth have astronomers doing a double-take after pinpointing its location near Neptune's equator, a region where no bright cloud has been seen before. The discovery was made at dawn on June 26 as UC Berkeley graduate student Ned Molter was testing the Keck telescope to see whether it could make useful observations during twilight, a time most astronomers consider unusable because it's not dark enough.

New evidence in support of the Planet Nine hypothesis

Wed, 12 Jul 17 00:01:40 -0700

Last year, the existence of an unknown planet in our Solar system was announced. However, this hypothesis was subsequently called into question as biases in the observational data were detected. Now Spanish astronomers have used a novel technique to analyze the orbits of the so-called extreme trans-Neptunian objects and, once again, they point out that there is something perturbing them: a planet located at a distance between 300 to 400 times the Earth-Sun separation.

Stalagmites from Iranian cave foretell grim future for Middle East climate

Mon, 10 Jul 17 00:04:40 -0700

The results, which include information during the last glacial and interglacial periods, showed that relief from the current dry spell across the interior of the Middle East is unlikely within the next 10,000 years.

UA astronomers track the birth of a 'super-earth'

Mon, 10 Jul 17 00:14:50 -0700

'Synthetic observations' simulating nascent planetary systems could help explain a puzzle -- how planets form -- that has vexed astronomers for a long time.

First discovery of an exoplanet with SPHERE/VLT

Thu, 06 Jul 17 00:00:00 -0700

An international team of astronomers, including members of the University of Geneva (UNIGE), Switzerland, discovered an exoplanet by direct imaging using SPHERE, an instrument designed and developed by a consortium of 12 European institutes on the Very Large Telescope ESO, based in Chile. The instrument, which corrects in real time the terrestrial atmospheric turbulences and occults the light of the star, allows to take a real «photography» of the exoplanet.
