Fireworks, in space.

Or:
a peek behind the scenes of big camera with flash photographs that could be in space. But are really on earth (sorry to destroy the illusion that I don’t actually have a space ship with time travel!) This is wandering through a nature reserve that was once a farm.

Pandora: Tuning Up our Data on Exoplanet Atmospheres

<p>Launching a flagship-class mission like the Roman Space Telescope is always exciting

I dream of humanity expanding beyond our star system. However, even with all that optimism, we're still about 500 years away from any reliable 2-way trip to and from Alpha Centauri.

Even if we develop antimatter propulsion at scale, it would still take a century of refinement to make it viable for interstellar travel.

This is the spectroscopic transit of a #planet with an orbital period of 1.5 YEARS !! #HIP41378 🪐

In case you missed the great paper led by @sgrouffal (#ProudAdvisor), arXived over the summer, here is a recap'.

The planet HIP41378 f is a Saturn-sized transiting planet with an orbital period of 542 days. It means we can observe its transit only once every 1.5 years - it's actually once every 3 years from the ground as the host star is too close to the Sun (as seen from the Earth) every other transits.

With such a long orbital period and a nearly circular orbit, the transit event lasts 19 hours (!). Hence, from the ground, any observer could only observe a tiny fraction of the transit. To overcome this issue, back in 2022, we set up a worldwide collaboration of almost all high-resolution radial-velocity spectrographs across the globe. Over the same night, all the instruments observed the target HIP41378 at the time of planet'f transit, allowing us to detect the Rossiter-McLaughlin (RM) effect.

The RM effect is measuring the planet's orbital obliquity, i.e. the angle between the orbital plane and the spin axis of the star. While this angle is ~0º in the solar system, for HIP41378 it reaches Ψ=~52º.
