An interstellar comet came from another solar system — so how different is it from the comets we already know?

In this clip, Dr. Cecilia Tubiana explains that 3I/ATLAS may be an interstellar visitor, but some of its properties look surprisingly familiar.

🔥 NEW: #Mercury orbits closest to the #Sun and receives nearly four times the #energy per unit area that Venus does, and it's the least reflective planet in the #SolarSystem.

Yet #Venus holds steady near 462°C day and night. Its #atmosphere, about 92 times thicker than #Earth’s and dominated by #carbondioxide, traps re-radiated heat.

Captured by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter, the light-toned layers have similar thicknesses and brightness, suggesting that the same kinds of material were deposited repeatedly over time.

New simulations show wind rising over the 19 km (12 mi) peak cools so fast that water vapor freezes directly into #ice crystals, skipping the dust particles that trigger cloud formation on #Earth. This homogeneous nucleation had never been observed in a planetary #atmosphere.

couldn't find a title. I think this has a spooky feel? Maybe it has the same sort of aesthetic as a sort of 60s - 70s science fiction that scared me when I was a kid. It's dark and there are evil-looking implements being used and idk I don't get a definite good guy sense from this character - that could be the cape and helmet of an evil alien villain. Weird energies flying around that don't seem normal, and maybe a vision of hell behind them. I'm spooked! 🤣

Captured by ALMA, this image of galaxy M83 depicts the light emitted by cold gas molecules, the ingredients of star formation. Images like this one allow us to map how the density and temperature of these gas clouds change in different locations within a galaxy. And in turn, understand whether stars form differently in different galactic environments.

The gleaming Trifid and Lagoon nebulae can be seen between our New Technology Telescope (left) and the ESO 3.6-meter telescope (right) at La Silla.

Their red colour comes from hydrogen atoms ionised by young stars in these clouds. The Trifid nebula also shows a blue tint caused by dust reflecting the light of some of these stars.
