Heads up, a potential big shift in #cosmology: new analysis suggests the #universe’s expansion is slowing, not accelerating. That overturns 25+ years of consensus on #darkenergy. Let’s break down why this matters 🧪🔭 🧵 1/3

🔭🧪🎢 PhD Project focus: Exploring the Atmospheres of Uranus & Neptune with JWST

We're advertising this project with Prof Leigh Fletcher, using infrared spectral data to investigate the changing atmospheres of the ice giants

For details of all our PhD projects look here: le.ac.uk/study/resear... 🔭🧪🎢

Uranus and its classical satellites are shown on the left against a background of galaxies; Uranus and Neptune are shown on the right replete with reflective rings and clouds. NIRSpec and MIRI will be used to provide full spectroscopy of the Uranus and Neptune atmospheres.

A giant impact between proto-Earth and a planet called Theia produced the Moon. Hopp et al. use isotopic measurements of lunar samples and cosmochemical modelling to show that Theia formed in the inner Solar System, probably closer to the Sun than Earth. ☄️ #planetsci

Is there really a “dark side” of the Moon?

#AskEthan

The phrase "dark side of the Moon" used to refer to the Moon's unseen, away-facing side: the far side.

But there is a "dark side" after all, just not where you'd expect.

Ask Ethan: Is there really a "dark side" of the Moon?
One side of the Moon always faces us: the near side. The "dark side" of the Moon began as a mere metaphor, but today, science can weigh in.

Our next ‘medium’ mission under #Voyage2050 is yet to be decided.

Three finalists, M-Matisse, Plasma Observatory and Theseus, are being further studied at the moment. One of them will be selected for implementation as the newest addition to our space science mission fleet.

1/ #CM25 🔭
An infographic-style visual with a black background and six circles following a timeline. The title is 'How are we selecting our next medium science mission?'. The red circles include the text as follows: November 2021 – Call for mission proposals; February 2022 – 27 first stage proposals; July 2022 – 10 second stage proposals; November 2022 – 5 proposals for pre-study; November 2023 – 3 proposals for further study; 1 M-CLASS MISSION. The first four circles are a faint red, the circle labelled 'November 2023' is brighter red, and the circle labelled '1 M-CLASS MISSION' is greyed out.

NEWS: Researchers used the James Webb Space Telescope to refine the orbit of two Wolf-Rayet stars—named for the Egyptian god of chaos—to a lengthy 190 years and confirmed a third star carves their ongoing carbon dust ejections. 🔭 🧪 (1/6) 🧵
Four dust shells expand away from three central stars that appear as a single pinpoint of light. The innermost shell is smallest, like the size of a thumbprint, and brightest. It is yellow and forms a backward lowercase e. A line at 3 o’clock swoops to the bottom-left in an arc that ends at 8 o’clock. A second line at 9 o’clock dips down to start, but then goes straight up, angling around the top. The second shell, about the size of a fist, is orange and has looser arcs. One appears from 4 to 7 o’clock. A brighter orange triangle appears from 10 to 12 o’clock. Its outer edges overlap, forming a rough circle. The third shell extends almost to the edges and is semi-translucent red, with similar arcs and a darker red line that also forms a faint triangle at top left. The widest shell is faintest and at the edges. A semi-transparent blue appears across the scene. A larger foreground star with spikes is at bottom left, and more distant stars and galaxies are strewn across the black expanse of space.
