This artist’s conception depicts V1674 Herculis, a classical nova hosted in a binary star system that is made up of a white dwarf and dwarf companion star. Scientists studying this nova have detected non-thermal emission, a departure from the historical belief that these systems produce only thermal emissions. Credit: B. Saxton (NRAO/AUI/NSF)

All three versions of AstroPix sensor chips are on display from the oldest on the left to version 3 on the right. Version three, which began testing in April 2023 has bigger pixels and improved functionality. Goddard’s Astropix team includes members around the world working together to develop and test a next generation gamma-ray detector. (Image credit: Regina Caputo)

Artistic illustration of OJ287 as a binary black hole system. The secondary black hole of 150 million solar masses moves around the primary black hole of 18 billion solar masses. A disk of gas surrounds the latter. The secondary black hole is forced to impact on the accretion disk twice during its 12-year orbit. The impact produces a blue flash which was detected in February 2022. In addition, the impact also induces the secondary black hole to bright bursts of radiation several weeks earlier, and these bursts have also been detected as a direct signal from the secondary black hole.

This infrared image from NASA’s James Webb Space Telescope (JWST) was taken for the JWST Advanced Deep Extragalactic Survey, or JADES, program. It shows a portion of an area of the sky known as GOODS-South, which has been well studied by the Hubble Space Telescope and other observatories. More than 45,000 galaxies are visible here.
