New rocky planet with thick atmosphere, detected

Published

on

A thick atmosphere has been detected around a planet that’s twice as big as Earth in a nearby solar system, researchers reported Wednesday.
The so-called super Earth — known as 55 Cancri e — is among the few rocky planets outside our solar system with a significant atmosphere, wrapped a blanket of carbon dioxide and carbon monoxide. The exact amounts are unclear. Earth’s atmosphere is a blend of nitrogen, oxygen, argon and other gases.

“It’s probably the firmest evidence yet that this planet has an atmosphere,” said Ian Crossfield, an astronomer at the University of Kansas who studies exoplanets and was not involved with the research.

The research was published in the journal Nature.

Super Earth refers to a planet’s size — bigger than Earth but smaller than Neptune. The boiling temperatures on this planet — which can reach as hot as 4,200 degrees Fahrenheit (2,300 degrees Celsius) – mean that it is unlikely to host life.

Instead, scientists say the discovery is a promising sign that other such rocky planets with thick atmospheres could exist that may be more hospitable.

The exoplanet 41 light years away is eight times heavier than Earth and circles its star Copernicus so closely that it has permanent day and night sides. A light-year is nearly 6 trillion miles (9.7 trillion kilometers). Its surface is encrusted with magma oceans.

To identify the makeup of its atmosphere, researchers studied Webb Space Telescope observations before and after the planet passed behind its star.

They separated the light emitted from the planet versus its star and used the data to calculate the planet’s temperature. There’s evidence the planet’s heat was being distributed more evenly across its surface – a party trick atmospheres are known for.

Gases from its magma oceans may play a key role in holding its atmosphere steady. Exploring this super Earth may also yield clues to how Earth and Mars might have evolved first with magma oceans that have since cooled, scientists say.

“It’s a rare window,” said Renyu Hu, a planetary scientist at NASA’s Jet Propulsion Laboratory, who was part of the research. “We can look into this early phase of planet evolution.”

Mount Etna erupts as large plumes rise from volcano

Published

By

Italy’s Mount Etna has erupted, with large plumes of ash and smoke seen rising from the volcano.

Images and video from the island of Sicily showed volcanic material spilling out of the volcano on Monday morning.

A number of explosions of “increasing intensity” were recorded in the early hours on Monday morning, Italy’s National Institute of Geophysics and Volcanology (INGV) Etna Observatory said.

The full scale of the eruption is currently unclear and disruption appears to be minimal.

Mount Etna is one of the world’s most active volcanoes, so eruptions are not uncommon and its outbursts rarely cause significant damage or injury.

Ukraine drones strike bombers during major attack in Russia

A Ukrainian drone attack destroyed more than 40 Russian planes deep in Russia’s territory, a Ukrainian security official told The Associated Press on Sunday, while Russia pounded Ukraine with missiles and drones a day before the two sides meet for a new round of direct talks in Istanbul.

The official, who spoke on condition of anonymity to disclose operational details, said the attack took over 18 months to plan and execute and was personally supervised by Ukrainian President Volodymyr Zelenskyy.

The operation saw drones transported in containers carried by trucks deep into Russian territory, he said. The drones reportedly hit 41 planes stationed at several airfields on Sunday afternoon, including A-50, Tu-95 and Tu-22M aircraft, the official said. Moscow has previously used Tupolev Tu-95 and Tu-22 long-range bombers to launch missiles at Ukraine, while A-50s are used to coordinate targets and detect air defenses and guided missiles.

Russia’s Defense Ministry in a statement confirmed the attacks, which spanned five airfields. The FPV drones damaged aircraft and sparked fires on air bases in the Irkutsk region, more than 2,500 miles from Ukraine, as well as Russia’s northern Murmansk, it said. Strikes were repelled in the Amur region in Russia’s Far East and in the western regions of Ivanovo and Ryazan, the ministry said.

The attack came the same day as MR. Zelenskyy said Ukraine will send a delegation to Istanbul for a new round of direct peace talks with Russia on Monday.

In a statement on Telegram, Mr. Zelenskyy said that Defense Minister Rustem Umerov will lead the Ukrainian delegation. “We are doing everything to protect our independence, our state and our people,” Mr. Zelenskyy said.

Ukrainian officials had previously called on the Kremlin to provide a promised memorandum setting out its position on ending the war before the meeting takes place. Moscow had said it would share its memorandum during the talks.
