Another first! Our Parker Solar Probe flew through an eruption from the Sun, and saw it “vacuuming up” space dust left over from the formation of the solar system. It's giving @NASASun scientists a better look at space weather and its potential effects on Earth. go.nasa.gov/46dNmTF

Cornell University Chronicle: ‘Thermometer’ Molecule Confirmed on Exoplanet Wasp-31B news.cornell.edu/stories/202…

‘Thermometer’ molecule confirmed on exoplanet WASP-31b | Cornell Chronicle

Chromium hydride, a molecule that’s relatively rare and particularly sensitive to temperature, is useful as a “thermometer for stars,” according to astronomer Laura Flagg in published research.

We found a shining mirror in the desert ! Glass and metal clouds on a planet that shouldn't be there makes LTT9779b shiner than Venus. How is that possible ? How do we know this ? Thread about our last Hoyer et al. paper aanda.org/articles/aa/full_h…

Can you spot your reflection in this exoplanet?🪩 Our @ESA_CHEOPS mission has spotted an ultra-hot planet outside of our Solar System which is covered by reflective clouds of metal, making it the shiniest exoplanet ever found. 👉 esa.int/Science_Exploration/…

Tuttu naama @Ursa_ry Tähdet ja avaruus -lehdessä. Se ei toki ole yllätys, kirjoitin jutun itse tutkijanvierailustani Chilen Santiagoon. Kanssani kuvassa @ProfDoubleJ

New Results! 🌟Stars making significant vertical excursions from the Milky Way plane host fewer super-Earths and sub-Neptunes. Metallicity alone cannot explain this intriguing observation. Galactic influences leave their mark on the planet population. arxiv.org/abs/2305.13389 🧵

After hearing about a recent evidence of active volcanism on #Venus. I decided to make a quick painting of erupting Maat mons on Venus. I really hope that this discovery will revive the #VERITAS mission, or at least keep it alive.

New Nature paper provides evidence that science has become less innovative since the 1950s. The authors suggest reversing the trend by: 1. reading widely, 2. focusing less on quantity of papers, & more on research quality, 3. taking year-long sabbaticals. nature.com/articles/s41586-0…

Yesterday I spent hours capturing this: an intricately detailed photo of the sun shot using a specially modified telescope. Here it is in the full 164 Megapixels, so you can zoom into every nitty gritty detail. That sunspot group on the top is currently pointed right at Earth!

Say hello to two new nearby potentially habitable exoplanets! GJ 1002, a tiny red-dwarf, hosts two Earth-mass planets. The article, led by @AlexSM10000ft and written in collaboration with @CARMENES_exopl, is available now on @arxiv arxiv.org/pdf/2212.07332.pdf

Today's an exciting day as we are able to finally present the MillenniumTNG (MTNG) project, a collaboration between MPA, Harvard, & Durham that has been a long time in the making. One of our goals has been to combine volume & resolution to enable impressive dynamic range, [1/9]

Today we present TOI-969! A planetary system around a late-K-dwarf with a hot-mini-Neptune in the desert and and long-period (>4.5yr) eccentric giant. Dynamics, internal structure, atmospheric escape, everything in a single paper! Some insights 👇 arxiv.org/abs/2210.08996

The results are in. @NASA crashed the #DARTMission into asteroid #Dimorphos. They altered its orbit by 4%. Orig. orbit around central 🪨: 11hr 55mins Models expected: a few-10 mins difference Post impact: 11hr 23mins. A 32 min orbital change! 👈@NOIRLabAstro 👉@HUBBLE_space

Live Now: #DARTMission experts discuss early results from the spacecraft’s planned impact with asteroid Dimorphos — the world’s first #PlanetaryDefense test. Remember: DART is a test and there are no known asteroid threats to Earth. xitter.cf/i/broadcasts/1nAJErXny…

We are very happy to release today a very insteresting paper lead by our colleague Susana Barros (from @IAstroPT) on a five (5!!) planets system with three of them having sub-Earth (sub-Earth!!) masses. A few ideas on this great #ESPRESSO discovery: 🧵👇 doi.org/10.1051/0004-6361/20…
