NASA’s TESS Enables Breakthrough Study of Perplexing Stellar Pulsations

Sound waves bouncing around inside a star cause it to expand and contract, which results in detectable brightness changes. This animation depicts one type of Delta Scuti pulsation — called a radial mode — that is driven by waves (blue arrows) traveling between the star’s core and surface. In reality, a star may pulsate in many different modes, creating complicated patterns that enable scientists to learn about its interior.

Aeolus goes public

Delivering new information about Earth’s winds, ESA’s Aeolus mission has already been hailed a success. Today, this remarkable satellite mission has yet again achieved new heights: its data are now being distributed publicly to forecasting services and scientific users in less than three hours of measurements being made from space.

A bent bridge between two galaxy clusters

A new study, based on data from ESA’s XMM-Newton and NASA’s Chandra X-ray observatories, sheds new light on a three million light-year long bridge of hot gas linking two galaxy clusters, whose shape is being bent by the mighty activity of a nearby supermassive black hole.

Shedding light on the ocean’s living carbon pump

Phytoplankton play a crucial role in ocean biology and climate. Understanding the natural processes that influence phytoplankton primary production, and how they are changing as the planet warms, is vital. A new study, using data from the European Space Agency’s Climate Change Initiative, has produced a 20-year time-series of global primary production in the oceans – shedding new light on the ocean’s living carbon pump.
