Bonse+ present a new high contrast imaging algorithm “4S - Signal-Safe Speckle Subtraction” demonstrated with the pre-recovery of the exoplanet AF Lep b from 2011 NaCo data. The software webpage has an interactive figure where you can play with and see the improvement over PCA. Nice! #astrodon 🔭🪐 https://arxiv.org/abs/2406.01809
Some planets are born alone, live alone, and die alone. The ESA's Euclid space telescope just found a nest of these loners in the constellation Orion.
At least the rogue planets have chosen a gorgeous spot to go about their business: This is where the newfound worlds are hanging out (toward the top of the image).

#JWST is often cited for its amazing work with galaxies, BUT LOOK AT IT DISSECTING UP THE CRAB NEBULA AND SHOWING US STAR GUTS FROM A 1000-YEAR OLD STELLAR DETONATION.
Wow! Look at the pulsar!
So epic that we can see this detail, the different structures, elements, velocities, energies, etc. from an event that Chinese and Japanese astronomers witnessed and documented 1000 years back.
We're connected through time with this event to them!
I finally got a chance to interview fellow PhD'er Sarah Caddy from our faculty about this excellent new research and looking at stars and satellites (like the ISS) DURING DAYLIGHT HOURS!
THey're using a telescope called 'The Huntsman' and look how many eyes it has 🕷️🔭
Sure #academia can be toxic at times and all of that.
Also:
this week I sat several times together with colleagues from Russia and Ukraine to discuss future possible projects.
an iranian told me how it was to be in Tehran at the end of April, when the Isreel-Iran situation escalated.
yesterday at my dinner table there were 1. an italian 🙋♂️ 2. a german 3. a brazilian 4. a kroatian 5. an iranian , and it was awesome to discuss the state of the world from all points of views.
Soon the telescope platform at ESO's Paranal Observatory in #Chile will look very different at night: all four of the 8.2 m telescopes of the VLT will be equipped with lasers! This is one of the ongoing upgrades of the GRAVITY+ instrument, which will allow us to study black holes, stars and planets like never before.
Did you know that it's actually NASA/ESA/CSA James Webb Space Telescope? Even though it is often referred to as "NASA" only.
European Space Agency #ESA has contributed the NIRSpec instrument, half of the MIRI instrument, and the launch (including the payload adapter & launch site services) and has 15 scientists working at the science and operations center. #CSA, the Canadian Space Agency, has contributed the NIRISS instrument.
After crisis in interstellar space, stream of Voyager 1 data resumes. Before its computer crashed, the venerable NASA probe may have entered mysterious new region beyond the Solar System.
