Researchers at Southwest Research Institute (SwRI) are examining Saturn's largest moon, Titan, to determine its tidal dissipation rate-the energy lost as it interacts with Saturn's immense gravitational field. Insights into this process provide valuable clues about Titan's internal composition and its orbital development over time.

Astronomers analyzing data from the Murchison Widefield Array, a radio telescope in Western Australia, encountered an unexpected anomaly. Instead of deep-space radio signals from over 13 billion years ago, they detected a terrestrial television broadcast-despite the telescope's location in a designated radio quiet zone designed to minimize signal interference.

Solar Orbiter ready for close encounter with Venus
Tuesday, 18 February 2025 08:00
The European Space Agency (ESA) is ready to guide the ESA/NASA Solar Orbiter spacecraft through its closest encounter with Venus so far.
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.
Studying the Sun’s poles will improve our understanding of solar activity, space weather, and the Sun-Earth connection.
