Journey with us to the star that exploded twice! 🚀
The remains of supernova SNR 0509-67.5 are all that is left of this star. Our VLT found out that it suffered a pair of explosive blasts, shedding new light on some of the most important explosions in the Universe.

M2-9, the Twin Jet Nebula, is a bipolar planetary nebula shaped by high-speed gas jets moving over 200 miles/sec. Formed about 1,200 years ago, it likely originates from a close stellar pair and a dense disk that channels gas into jet-like outflows. Credit: NASA, Bruce Balick et al.

Do referendums lead citizens to know more about the issue of the referendum after it was shockingly defeated by the public? I answer this question based on the EU Constitution referendum here: doi.org/10.1080/0703... a short thread below
Telltale Signs of Fraudulent Academic Research
Two scientists and an editor spent six months investigating so-called paper mills, which churn out bogus scientific papers that impede actual research on lifesaving breakthroughs.

At the centre is a thin vertical cloud known as Lynds 483 (L483) that is roughly shaped like an hourglass with irregular edges. The lower lobe is slightly cut off. The top lobe is seen in full, petering out at the top.

This is a cropped, close-up image of the planet Venus, taken by the Parker Solar Probe’s WISPR instrument. The image shows a crescent Venus against the black backdrop of space, with the edge of the planetary limb clearly defined. The crescent is illuminated by sunlight, transitioning from a bright, almost white glow at the top right edge to a subtle, golden yellow that dominates the majority of the illuminated area, before fading into the darkness of the planet's night side at the bottom left. The distinct variations in brightness and texture across the crescent suggest cloud formations or atmospheric layers. A bright, flaring light source is visible at the top right corner, likely the Sun, which contributes to the illumination of the crescent. The overall composition emphasizes the stark contrast between the luminous crescent and the surrounding darkness, highlighting the curvature and celestial context of Venus.
This is the clearest photo ever taken of Venus.

This is the closest image of Saturn ever captured by the Cassini spacecraft. It shows the planet in a majestic and serene light, with its rings in the foreground. The planet's golden hues are highlighted by the sunlight filtering through its upper atmosphere. A notable feature is the intriguing hexagonal storm at the north pole, a unique weather phenomenon in our solar system. The image provides an unparalleled, close-up perspective, inviting viewers to appreciate the intricate details of Saturn's cloud bands and the sheer vastness of its ring system. It is a stunning portrayal of the beauty and complexity of this gas giant, captured from a vantage point closer than any human-made probe has ventured before.

The JuliaCon Global 2025 Diversity, Equity, and Inclusion (DEI) Committee is excited to announce a Proprosal-A-Thon for writing your JuliaCon Global 2025 proposal! The call for proposals is out right now, and we are looking for both talks and posters for JuliaCon Global 2025. We will run the event during two days in different time zones Sunday January 26th at 4pm CET. If you are curious about the process of writing and submitting a proposal (you don’t need an idea yet!), we encourage you to attend! The event will start with a 30-minute presentation on the process, followed by an hour of office hours where you can ask individual questions. This event is intended to help community members who are first-time presenters.
Submitting to JuliaCon Global 2025 for the first time, or know a student / young researcher who is interested?
Join us for our second Proposal-a-Thon at this link on Sunday 4PM CET / 10AM EST: app.gather.town/events/aONRc...
This Near-Infrared Camera (NIRCam) image shows the Bullet Cluster, a powerful astronomical event resulting from the collision of two galaxy clusters. The image features a bright, central core with a distinct pinkish hue, representing the hot gas. Surrounding this core are countless individual galaxies, seen as bright white and yellowish dots, scattered across the dark background of space. Extending outwards from the center are faint, blue streaks, indicative of the superheated gas that was pulled away during the collision. The overall scene conveys a sense of immense energy and cosmic dynamism.
