Scientists find two huge red rocks in the asteroid belt that shouldn’t be there

Posted by in categories: materials, space

Scientists have found two huge, red objects in the asteroid belt that they believe are not supposed to be there – both of which have “complex organic matter” on their surfaces.

These two asteroids, called 203 Pompeja and 269 Justitia, were discovered by Jaxa, the Japan Aerospace Exploration Agency. Pompeja is approximately 110 kilometres wide, while the smaller Justitia has a diameter of only 55 kilometres.

Found in the cluster of rocks between Mars and Jupiter, these two objects are distinctly different from their neighbours. Both Pompeja and Justitia reflect more red light than other surrounding asteroids due to the increased presence of complex organic material on their surface – such as carbon or methane.

A ‘Very Exciting’ unique exoplanet has more water than earth

Posted by in category: space

The CHEOPS satellite accidentally spotted a rare exoplanet with no known equivalent. The satellite detected this unique exoplanet while looking for two exoplanets in a bright nearby star system.

This planet called ‘Nu2 Lupi d’ is located 50 light-years away in the constellation Lupus (Latin for Wolf), around a star called Nu2 Lupi. It is about 2.5 times the size of Earth and almost 9 times its mass.

What’s more, scientists used measurements with archival data from other observatories and numerical models to characterize the density and composition of the planet and its neighbors. They found that the planet has a rocky interior. It has far more water than the Earth. However, the water is not liquid; instead of taking high-pressure ice or high-temperature steam, making the planets uninhabitable.

Scientists capture most-detailed radio image of Andromeda galaxy to date

Posted by in categories: physics, space

Scientists have published a new, detailed radio image of the Andromeda galaxy—the Milky Way’s sister galaxy—which will allow them to identify and study the regions of Andromeda where new stars are born.

The study—which is the first to create a radio image of Andromeda at the of 6.6 GHz—was led by University of British Columbia physicist Sofia Fatigoni, with colleagues at Sapienza University of Rome and the Italian National Institute of Astrophysics. It was published online in Astronomy and Astrophysics.

“This image will allow us to study the structure of Andromeda and its content in more detail than has ever been possible,” said Fatigoni, a Ph.D. student in the department of physics and astronomy at UBC. “Understanding the nature of physical processes that take place inside Andromeda allows us to understand what happens in our own galaxy more clearly—as if we were looking at ourselves from the outside.”

NASA detects water vapor on Jupiter’s Ganymede — the largest moon in the solar system

Posted by in category: space

Reviewing the images of Ganymede’s aurora, the team discovered that, as the moon’s surface temperature rises and falls throughout the day, it becomes warm enough around noon near the equator for sublimation to occur, releasing water molecules.

“In a wider sense, this discovery shows that often one needs to know what to focus on when analyzing data. The signal from H2O was present in the HST images since 1998,” said lead author Lorenz Roth. “Only with additional information through new data and predictions from theoretical studies, we knew what to look for and where to search for it. There are likely many more things to discover in the gigantic dataset that the Hubble Space Telescope has accumulated over its three decades in space.”

NASA’s Fermi Spots a Weird Pulse of High-Energy Radiation Racing Toward Earth

Posted by in category: space

On August 26, 2020, NASA’s Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books – the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen.

GRBs are the most powerful events in the universe, detectable across billions of light-years. Astronomers classify them as long or short based on whether the event lasts for more or less than two seconds. They observe long bursts in association with the demise of massive stars, while short bursts have been linked to a different scenario.
