☄️ 🔭 The impact probability of asteroid 2024 YR4 has dropped from 2.8% to 0.16%. Thanks to new observations, Earth is now at the edge of our shrinking ‘uncertainty window.’ If this trend continues, the risk may soon reach 0%.

Listen to the #BepiColombo spacecraft as it flew past #Mercury on 8 January 2025. This sixth and final flyby used the little planet's gravity to steer the spacecraft on course for entering orbit around Mercury in 2026. www.youtube.com/watch?v=GA6i...

Flyby success! Solar Orbiter swept past Venus last night, using the planet's gravity to adjust its orbit and grant it a new view of the Sun's polar regions. Everything went as planned 🕹️🛰️✅

#Einstein Probe captured the X-ray flash from a very odd celestial couple. The pair consists of a hot star, more than 10 times larger than our Sun & a small compact white dwarf, with a mass similar to our star. Find out more 👉 www.esa.int/Science_Expl... 🔭🧪 #extragalactic #highenergyastro

Solar Orbiter is getting ready for a close encounter with #Venus. Today’s flyby will be the first to significantly ‘tilt’ the spacecraft’s orbit and allow it to see the #Sun’s polar regions, which cannot be seen from Earth. Get the details 👉 www.esa.int/Enabling_Sup... 🔭

🎵 If you warp space due to the combined massive gravitational field of billions of stars in a chance alignment with Earth then you should've put a ring on it 🎶 badastronomy.beehiiv.com/p/einstein-p... 🔭🧪

Hubble is searching for an imposter in the spiral galaxy UGC 5460! 🥸 This galaxy hosted two recent supernovae, one of which might actually turn out to be an impostor called a luminous blue variable 👉 esahubble.org/images/potw2...

Not exactly as some of our followers expected it, but here comes the ESA #Juice bar update 😀 The mission continues to stay close to the Sun until March. The distance between Juice & Earth is increasing quickly. It now takes 9 minutes for telemetry data to travel one way. 1/2 #planetsci

Our dark Universe detective 🕵️ Euclid has discovered a stunning Einstein ring! 💍 It surrounds galaxy NGC 6505, which is acting as a gravitational lens, bending light from a distant galaxy behind it. Why is this rare phenomenon so useful for scientists? 👉 www.esa.int/Science_Expl... 🔭🧪 #cosmology

ESA’s mission, LISA, will capture and study ripples in the fabric of spacetime. These ripples, which we call gravitational waves, are emitted during some of the most powerful events in the Universe. Find out more at 👉 esa.int/lisa

☄️ We aren’t just waiting for an asteroid to strike. We are taking active measures to help Earth defend itself against a potential impact. Which is why we are endorsing the the United Nations' designation of 2029 as the International Year of Asteroid Awareness and Planetary Defence.
