ESA Hubble and Webb Space Telescopes’ Post

The NASA/ESA/CSA James Webb Space Telescope and NASA/ESA Hubble Space Telescope have affirmed the Universe’s expansion rate, but a puzzle still persists. Why does the Hubble value do not agree with other measurements that imply that the Universe was expanding faster after the Big Bang? It's now up for other telescopes such as ESA's #Euclid to take up the baton and solve this cosmic mystery... 👉https://lnkd.in/efJpdDpj ESA Hubble and Webb Space Telescopes

🆕 The NASA/ESA/CSA James Webb Space Telescope has found candidates for the first young brown dwarfs outside the Milky Way! 🟤🔬 🔴 About 3000 brown dwarfs – free-floating, more massive cousins of giant gas planets – had previously been discovered, all within our own galaxy. 🔴 NGC 602 is a star cluster that lies near the outskirts of the Small Magellanic Cloud, a satellite galaxy roughly 200,000 light-years from Earth. Hubble previously revealed that the cluster contains very young, low mass stars… 🔴 So astronomers used Webb to take a closer look. This revealed candidates for the first young brown dwarfs outside our galaxy. 🔴 The results fit well with the theory that brown dwarfs form the same way as stars, but don’t accrete enough mass to become fully fledged stars ⭐ Read more about it here: https://ow.ly/PUaI50TPKRl #WebbSeesFarther 📷 ESA/Webb, NASA & CSA, P.

Thank you NASA! The Butterfly Nebula from Hubble. Stars can make beautiful patterns as they age. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot, shining brightly in visible and ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up was recorded by the Hubble Space Telescope and is processed here to show off remarkable details of the complex planetary nebula, highlighting in particular light emitted by oxygen (shown as blue), hydrogen (green), and nitrogen (red). NGC 6302 lies about 3,500 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius). Planetary nebulas evolve from outer atmospheres of stars like our Sun, but usually fade in about 20,000 years.

International Space Station slipping across the Moon's face as it flies by at 8 kilometers per second (8th Mar 2024) The moon and the earth rotate synchronously, so people on Earth can only see the same side of the moon throughout their lives. Because the moon also rotates, people on Earth cannot see the other side (see Figure L1a). There are also days when the moon faces away from the sun. It was pitch black at this time. Even if the International Space Station orbited the moon, it was pitch dark for part of the time because it faced away from the sun. The gravitational force of two large masses is equal to the centripetal force required for small objects to move accordingly. Therefore, the moon falls at the Lagrangian point between the sun and the earth (L1, L1a & L3). NASA announce (James Webb) The Abel Space Telescope is also a Lagrangian point. (See attached picture L1, L2 & L3). I wonder if there is a chance to see the other side of the moon? Ref: Please refer to the link for details - https://lnkd.in/g-DcRHRk

Reviving a Legend: The Spitzer-Resurrector Mission 💫 In 1979, NASA - National Aeronautics and Space Administration's visionary Great Observatory program brought us the Hubble, Compton, Chandra, and Spitzer telescopes, each opening new windows to the Universe. The Spitzer Space Telescope, launched in 2003, embarked on a remarkable journey exploring the Universe until its mission concluded in 2020 when NASA placed the telescope in safe mode. But the story doesn't end there. In 2028, the United States Space Force has the opportunity to demonstrate satellite servicing by telerobotically reactivating Spitzer for astronomical observations, and in a separate experiment, carry out novel Space Weather research and operations capabilities by observing solar Coronal Mass Ejections. This will be accomplished by launching a small satellite, the Spitzer-Resurrector Mission, to rendezvous with Spitzer in 2030, positioning itself around it, and serving as a relay for recommissioning and science operations.

🆕 The NASA/ESA/CSA James Webb Space Telescope has spotted evidence for the most distant black hole merger yet! 👀 🔴 Supermassive black holes with masses millions to billions of times that of our Sun are likely to have influenced the evolution of their galaxies – but much about them remains unknown, such as how they grow to such a size. 🔴 Now, Webb has uncovered evidence for an ongoing merger of two galaxies and their massive black holes 🕳️ when the Universe was just 740 million years old. This phenomenon has never been detected so early in the Universe. 🔴 The findings show that black holes can grow rapidly through mergers, and that these massive black holes have been shaping the evolution of galaxies since cosmic dawn. 🔴 Once these two black holes merge, they will also generate gravitational waves. Events like this will be detectable with the next generation of gravitational wave observatories, such as ESA's upcoming Laser Interferometer Space Antenna (LISA) mission.

James Webb Telescope- Unfolding the Universe! The James Webb Space Telescope, a marvel of modern technology, plays a pivotal role in unraveling the mysteries of the universe. This advanced tool, utilized by astrophysicists and astronomers, offers a unique vantage point to observe key stages in the evolution of our cosmos. With its cutting-edge capabilities, the Webb telescope enables the study of the transformation of initial stars into galaxies, the subsequent collisions and mergers of these galaxies into larger cosmic structures, thus shaping the universe as we perceive it today. This groundbreaking exploration holds the promise of delivering invaluable insights into the cosmic history that underpins our very existence. Moreover, it poses the profound question: are we truly alone in this vast universe?

Hubble Views a Vast Galactic Neighborhood This image from the NASA/ESA Hubble Space Telescope features a richness of spiral galaxies: the large, prominent spiral galaxy on the right side of the image is NGC 1356; the two apparently smaller spiral galaxies flanking it are LEDA 467699 (above it) and LEDA 95415 (very close at its left) respectively; and finally, IC 1947 sits along the left side of the image.

What is the concentration of atomic oxygen in Venus' atmosphere? What makes planetary nebulae, which form when stars die, so fascinating? What role do magnetic fields play in the birth of galaxies? These are just some of the #scientific questions that the flying observatory SOFIA helped to answer. The Stratospheric Observatory for Infrared Astronomy SOFIA explored space from November 2010 to September 2022. The observation flights are the result of a joint German-American project between the space agencies DLR and NASA. Scientific operations on the German side are coordinated by the Deutsches SOFIA Institut (DSI) at the Institute of Space Systems Universität Stuttgart - Institut für Raumfahrtsysteme (IRS) More about: https://lnkd.in/eA7WjeHn #UniversityofStuttgart.

The NASA/ESA Hubble Space Telescope has taken a close-up look at Jupiter’s Great Red Spot (GRS) 👀 🔴 Its latest observations were collected over 90 days between December 2023 and March 2024, as part of a program dedicated to the GRS. Hubble zoomed in on the GRS for a closer look at its size, shape, and subtle changes in colour. 🔴 This revealed that the GRS is not as stable as it might look, with many changes from day to day, including an oscillation in size which at present has no hydrodynamic explanation. 🔴 Astronomers hope that in the future other high-resolution images from Hubble might help identify the underlying cause of the oscillation.
