Humanity’s first space-based gravitational wave detector has received the go-ahead. The Laser Interferometer Space Antenna (LISA) mission, which consists of three spacecraft that together form a single gravitational wave detector, is a collaboration between NASA and the European Space Agency (ESA). It’s set to launch in the mid-2030s. The adoption of LISA was announced by […]
Observations have revealed the first-ever seismic waves seen in an ancient galaxy, possibly offering new insight into the origins of our very own Milky Way. The galaxy, known as BRI 1335-0417, is more than 12 billion years old, making it the oldest and farthest known spiral galaxy in our universe. Using the Atacama Large Millimeter/submillimeter […]
Scientists are still hunting for the source of the faint, persistent hum of gravitational waves discovered reverberating through the Milky Way last year. Those waves could point to more than one tantalizing source, new research suggests. The discovery team, the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, collaboration, strongly suspects the ripples in […]
