Scientists have discovered a new earth sized planet with 17 hour year. It will be interesting to know what type of planet is it.

In an exciting development, scientists have discovered an Earth-sized exoplanet, SPECULOOS-3 b, orbiting an ultra-cool dwarf star approximately 55 light-years from Earth.

“I don’t care if we burn $50 billion a year, we’re building AGI,” says Sam Altman He doesn’t care about burning the planet either. Typical irresponsable megalomania. https://analyticsindiamag.com/i-dont-care-if-we-burn-50-billion-a-year-were-building-agi-says-sam-altman/ in danger

A COSMIC ARROW PIERCED PLUTO'S HEART — IS IT STILL THERE BENEATH THE SURFACE?

A giant impact likely formed Pluto’s heart-shaped basin, Sputnik Planitia. A big chunk of the impactor’s core might still be buried under the ice.

#TopicOfTheday: #EarthDay 2024 is themed '#Planet vs. #Plastics' to draw attention to the pollution caused by the increased use of plastics.

The exponential increase in plastic production from a mere two million tons in 1950 to over 450 million tons annually today represents a dire environmental crisis requiring immediate action.

Today is .🌏

In 2019 I came across a post in a French Facebook group. Franck Deschamps was looking for someone to write the music for his lyrics, Petite planète. 🌍

I immediately liked them and wrote the song and arranged it. It was my first production from home.

Today it’s a fundraiser on . Please consider donating to Greenpeace. 🌎

Thank you! 🙏

Saturn's moon Enceladus top target for ESA

"A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyses them for hints of life."

Good morning friends!

We’re back with#formation and this morning starting with Charles Law on embedded planets.

Charles stresses how much has revolutionised the field providing a wonderful pictures of discs. Nevertheless, resolving planets embedded in these discs is pretty hard. But chemistry is our saviour, making signatures of the planet observable with .

We start with the disc HD 169143 b - funny I worked with data from this disc for my bachelor’s thesis.

Next up, we’ve got Kiersten Boley on the first evidence of the metallicity cliff in the formation of super-Earths.

The first stars were metal poor, so there were not enough metals to form planets via core accretion. So the question comes up: when did we start forming planets?

Already back in 1996, after finding 4 planets, people started doing statistics ;) in particular looking at how metallicity links to .

We’re back with direct imaging with Masayuki Kuzuhara.

They used the to observe nearby accelerating stars and search for substellar companions.

They discovered 4 substellar companions, one of which is the brown dwarf HIP 21152 B. The spectrum reveals water and methane. They further modelled the orbit, giving them a dynamical mass of around 28 Mjup.

Next up, we’ve got Thomas Vandal on as a tool to understand .

Directly imaged planets - albeit few - are crucial to help us understand planet formation scenarios.

Using JWST aperture masking interferometry, they targeted two systems, as part of an exploratory program.

On particular finding is that the choice of reference star is important. Longer exposures are needed to study the planets (reaching contrast).

Next up, we’ve got Melanie Rowland on protosolar D/H abundance in the coldest brown dwarf.

In recent years, the detection of isotopologues has become a thing for exoplanets and brown dwarfs.

traces and . Rocky planets are thought to get their ratio from comets. Ice giants are also enhanced due to D-enriched ice, while the gas giants are not.

Brand new Science Magazine astronomy cover!

Featuring a infrared image of the Orion Bar, which separates parts of the Orion Nebula containing cool molecular gas (lower left) from those containing hot plasma (upper right). The latter are ionized by ultraviolet radiation from massive (located beyond the image). The strong ultraviolet radiation field heats protoplanetary disks around young stars in this region, dispersing the gas needed for formation.
