The Galileo Project was announced a month after the Pentagon released a report about unidentified aerial phenomena, which stated that their nature was unclear. An international team of scientists led by a prominent Harvard astronomer announced a new initiative Monday to look for evidence of technology built by extraterrestrial civilizations. […]

A new study led by A&S professor Tao Wen used a novel method of machine learning to explore the environmental impact of oil and gas drilling. A study led by EES professor Tao Wen is one of the first to use machine learning techniques to holistically assess general water quality […]

As marine heatwaves become more commonplace, coral reefs are expelling their microscopic and colorful algae and bleaching white. Scott Reef, Australia, April 2016.

When the core of massive star collapses, it can form a black hole. Some of the surrounding matter escapes in the form of powerful jets that rush outward at almost the speed of light in opposite directions, as illustrated here. Normally jets from collapsing stars produce gamma rays for many […]

In 1998, Hubble’s Space Telescope Imaging Spectrograph (STIS) took these first ultraviolet (UV) images of Ganymede, which revealed a particular pattern in the observed emissions from the moon’s atmosphere. The moon displays auroral bands that are somewhat similar to aurora ovals observed on Earth and other planets with magnetic fields. […]

Artist’s concept of Lucy Mission. Credit: SwRI In the 1970s four spacecraft began their one-way trips out of our Solar System. As the first human-built objects to ever venture into interstellar space, NASA chose to place plaques on Pioneer 10 and 11 and golden records on Voyager 1 and 2 […]
