Quasar’s Light Echoes After 6.73 Years

Quasar’s Light Echoes After 6.73 Years

Astronomers using the 1.2-meter Whipple Observatory to follow the brightness of a lensed galaxy for 14.5 years have calculated that the time delay between light arriving along the shortest and farthest paths is 6.73 years. Plus, DART, Hayabusa2, Juno, fast radio bursts, and This Week in Space History, we look back at NASA’s 1990s attempts to reach Mars.

Infrared Telescope Balloon Mission Gets Mini-JWST Mirror

While waiting for the launch and commissioning of JWST, engineers designed an infrared telescope with a 2.5-meter mirror that will fly onboard a large research balloon to nearly 40 kilometers in altitude. Plus, fast radio bursts, robotic ammonites, and this week in rocket history we look back at Telstar-1.

Second Repeating Fast Radio Burst Discovered

Second Repeating Fast Radio Burst Discovered

A second repeating fast radio burst was detected in 2019 by China’s FAST observatory and confirmed in 2020 by the Very Large Array. This latest discovery raises the possibility that there are two different types of FRBs. Plus, a SpaceX commercial launch, mission updates, neutron stars, and this week’s What’s Up.

Pulsars as the Particle Accelerators of the Universe

Pulsars as the Particle Accelerators of the Universe

Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake. Plus, missions close to home, large and distant objects, some pretty Hubble photos, and laser simulations of fast radio bursts.
