Using the Hubble Space Telescope, astronomers have discovered that the atmosphere of a relatively small planet outside the solar system is rich with water vapor. However, the planet's surface is hot enough to melt lead, meaning it's a steamy world inhospitable to life as we know it. The planet is just one of three Earth-like worlds orbiting this star, which appears to be around 6 billion years old. Though scientists have found water vapor in the atmospheres of many extra-solar planets before, the Hubble Telescope's observations of this hot and steamy world, designated GJ 9827d, represent the smallest exoplanet around which this vital element for life has been found thus far. The study of GJ 9827d with Hubble has marked the planet as a prime target for a follow-up investigation conducted with the James Webb Space Telescope (JWST). #galaxyaerosgh #space #spaceexploration #spacenews

Mysterious Mini-Neptunes in Unexpected Orbits | National Inst. of Natural Sciences This study discovered mini-Neptunes around four red dwarfs using observations from a global network of ground-based telescopes and the TESS space telescope. These four mini-Neptunes are close to their parent stars, and the three of them are likely to be in eccentric orbits. https://lnkd.in/dsRG5R3b

𝐀𝐬𝐭𝐫𝐨𝐧𝐨𝐦𝐞𝐫𝐬 𝐭𝐫𝐚𝐜𝐤 𝐰𝐞𝐚𝐭𝐡𝐞𝐫 𝐨𝐧 𝐚𝐧 𝐞𝐱𝐨𝐩𝐥𝐚𝐧𝐞𝐭 𝐭𝐡𝐚𝐭 𝐫𝐚𝐢𝐧𝐬 𝐠𝐞𝐦𝐬𝐭𝐨𝐧𝐞𝐬 Astronomers have taken a three-year-long view of an extreme heavy metal exoplanet called WASP-121b using the Hubble Space Telescope, enabling them to reconstruct its changing atmosphere and weather in a way that has never been done for a planet outside the solar system before. This revealed this violent and turbulent world is even more chaotic than scientists initially suspected. WASP-121b, a planet that is 1.75 times the size of Jupiter and orbiting so close to its host star that it completes an orbit in just 30 hours, which is one of the shortest orbits ever seen by astronomers.

Space exploration continues to push the boundaries of our understanding of the universe, with missions like the James Webb Space Telescope and Artemis program expanding our knowledge of the cosmos. Space exploration is unlocking the secrets of the universe, revealing new insights into our place in the cosmos. #SpaceExploration #JWST #ArtemisProgram

Space scientists at the University of Surrey will design a new telescope to better understand extreme space weather, thanks to £250,000 from the UK Space Agency - which could make flying safer. The Surrey team will develop plans for a new High Energy Proton Telescope, known as HEPTEL, which aims to measure the radiation caused by solar flares in space, before it is disrupted by the Earth’s atmosphere. It will monitor protons, which are the dominant particle type in cosmic rays and can stop electronic devices from working properly, especially those on aircraft. The benefits could also extend to interplanetary travel and the development of settlements on the Moon and Mars. https://ow.ly/LPzG50Q9N3t #SpaceWeather #SolarFlares #FlyingSafety #CosmicRays #space #research

✨ISRO today performed the final manoeuvre to put India’s Aditya-L1 space probe into a halo orbit around the Sun-Earth Lagrange’s Point 1 (L1), the solar space observatory’s final destination some 1.5 million-km from Earth, from where it will study the Sun for an expected period of five years. ISRO will now perform periodic manoeuvres to keep the spacecraft in the intended orbit so that it can employ the seven payloads it has carried to observe the photosphere, chromosphere, and the outermost layers of the Sun (the corona) using electromagnetic and particle detectors. Using the special vantage point of L1, four payloads will directly view the Sun and the remaining three payloads will carry out in-situ studies of particles and fields at the Lagrange point L1.🌟

How tiny are we REALLY? Ever feel insignificant? Our sun makes our planets look like pebbles! It's 1.3 MILLION times bigger than everything else in our solar system! That's where the incredible James Webb Space Telescope comes in. With its massive mirror, Webb will peer deeper into space than ever before, revealing hidden secrets and maybe even new worlds!
