TIRA Space Observation Radar Captures Last Images of ERS-2 Tumbling Through the Sky

Radar image of the satellite ERS-2 from February 19, 2024: Solar module intact. Credit: Fraunhofer FHRThe European Space Agency (ESA) and the joint Space Situational Awareness Centre commissioned Fraunhofer FHR to accompany the re-entry of the retired ERS-2 satellite. With its unique space observation radar TIRA (Tracking and Imaging Radar), the final orbits were measured with high precision and the last images of ERS-2 were generated. For the first time, changes in the structure during re-entry were captured in…

Ancient Stars Whisper Celestial Secrets in the Large Magellanic Cloud

This Hubble Space Telescope image features NGC 1841, a globular cluster within the Large Magellanic Cloud (LMC). Globular clusters like NGC 1841, characterized by their density and ancient stars, serve as cosmic fossils, revealing the complexities of early galactic development. Credit: ESA/Hubble & NASA, A. Sarajedini, F. NiederhoferNGC 1841 in the Large Magellanic Cloud showcases the early universe’s star formation, highlighting the role of globular clusters as cosmic fossils within satellite galaxies of the Milky…

ESA Satellite Returns to Earth [Video]

ESA’s ERS-2 satellite, launched in 1995, has concluded its mission by reentering Earth’s atmosphere over the North Pacific Ocean. (Artist’s concept of a satellite burning up in the atmosphere.) Credit: SciTechDaily.comMission complete. ESA’s second European Remote Sensing (ERS-2) satellite has reentered Earth’s atmosphere over the North Pacific Ocean. The satellite returned on February 21, 2024, at 18:17 CET (17:17 UTC) between Alaska and Hawaii.ERS-2 was launched almost 30 years ago, on April 21, 1995. Together with…

A Fiery Farewell to ESA’s Pioneering ERS-2 Satellite

ERS-2 was launched in 1995, four years after ERS-1, the first European Remote Sensing satellite. At the time, these two satellites were the most sophisticated European Earth observation spacecraft ever developed, delivering new information to study Earth’s land, oceans, atmosphere, and polar ice, as well as being called upon to monitor natural disasters such as earthquakes and floods. In 2011, the mission was retired and the spacecraft was reorbited into a safe disposal orbit in compliance with ESA space-debris mitigation…

How AI and Sentinel-1 Exposed 75% of Global Fishing Vessels

Map reveals fishing activity not publicly tracked around Portugal and Morocco. The map shows individual vessels detected by Sentinel-1 during 2017–2021, matched (blue) to known vessel positions from AIS broadcasts and unmatched vessels (orange). The vessels were classified as fishing or non-fishing with a deep-learning model. The national exclusive economic zones are overlaid.

This Is a Real Satellite Falling to Earth

Many Star Wars fans probably thought they were dreaming when the European Space Agency published images of what looked like a TIE starfighter in space. Alas, it wasn’t the Empire, but rather glimpses of a decades-old Earth observation satellite making its return home.Astronomers Could Soon Get Warnings When SpaceX Satellites Threaten Their ViewThe recent images of the satellite, known as the second European Remote Sensing satellite, or ERS-2, were taken by space tech company HEO using cameras onboard other satellites. ESA…

5,000 Pound European ERS-2 Satellite Falls to Earth

ERS-2, a satellite that revolutionized our perspective of our planet and understanding of climate change, was launched in 1995. After 13 years of orbital decay, mainly driven by solar activity, the satellite will now naturally reenter Earth’s atmosphere. ERS-2 is now expected to undergo atmospheric reentry and begin to break up on February 21, 2024. Credit: ESAERS-2 is expected to undergo atmospheric reentry and begin to break up today.Throughout its 16-year working life, the second European Remote Sensing satellite,…

Unveiling the Secrets of Star Formation in IC 3476

By ESA/Hubble February 18, 2024Hubble Space Telescope image of IC 3476, a dwarf galaxy 54 million light-years away in the constellation Coma Berenices. It is undergoing ram pressure stripping, a process that affects star formation. Although the galaxy appears calm, it’s experiencing heightened star formation in certain areas due to the ram pressure exerted by the intergalactic medium. Credit: ESA/Hubble & NASA, M. SunRam pressure stripping in IC 3476 boosts star formation in specific areas by compressing gas, despite…

XMM-Newton Spacecraft Detects Black Hole Winds Hindering Star Formation

This artist’s impression shows ultra-fast winds blasting out from the center of galaxy Markarian 817. These winds, moving at many millions of kilometers per hour, clear out interstellar gas from a vast region of space. Without this gas, the galaxy can’t form new stars and the black hole in the galactic center has little left to eat. Credit: ESAObservations reveal black holes can alter galaxies by ejecting gas, impeding star formation, with significant implications for understanding galactic evolution.Black holes are like…
