I look at a lot of space images, but this one made my eyes bug out like a cartoon character.

What you see here isn't a spiral galaxy, exactly. It's a spiral galaxy whose image was bent into a circle by the gravity of an elliptical galaxy visible at the center.

Warped space, right before your eyes!

This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a rare cosmic phenomenon called an Einstein ring. What at first appears to be a single, strangely shaped galaxy is actually two galaxies that are separated by a large distance. The closer foreground galaxy sits at the center of the image, while the more distant background galaxy appears to be wrapped around the closer galaxy, forming a ring.

Only eight #asteroids ☄️ have ever been detected before impact 💥 with #Earth’s atmosphere. The first of these discoveries took place in 📆 2008, and four were detected in just the last two years https://www.esa.int/Space_Safety/Planetary_Defence/Asteroid_2024_BX1_spotted_three_hours_before_impact

#Asteroid danger explained : "The main challenge stems from the population of middle-size objects, ranging from tens to hundreds of metres in diameter. There are a lot of these asteroids, and most have not been spotted yet." https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained

Electric propulsion systems are not #energy limited. An arbitrarily large amount of energy can be delivered (from a #solar ☀️ or #nuclear ☢️ power system) to a given mass of propellant so that the exhaust velocity (or specific impulse) can be much larger than that available from a #chemical propulsion system. Electric propulsion systems are termed " #power 🔋 limited" https://sci.esa.int/web/smart-1/-/34201-electric-spacecraft-propulsion?section=electric-versus-chemical-propulsion

Launch costs have fallen 95% 📉 (with another massive reduction expected in the coming years) thanks to reuse, improved engineering, and increased volumes.
