This color-composite mosaic of the central part of the Orion Nebula is based on 81 images from the European Southern Observatory (ESO) Very Large Telescope at the Paranal Observatory in Chile. The famous Trapezium stars appear near the center, amid the Trapezium Cluster, the very crowded home of more than a thousand young stars. Researchers will train Webb on this region to study phenomena associated with the birth of stars and planets.

Not very active: comparison of the brightness variations of the Sun with those of a typical Sun-like star.

A next-generation seismometer could be deployed autonomously, unlike the systems deployed in the past. In this photo, Apollo 12 astronaut Alan Bean carries the Apollo Lunar Surface Experiments Package to its deployment site on the Moon.

Realignment of open and closed magnetic field lines on the Sun, called interchange reconnection, could explain the magnetic "switchbacks" observed by Parker Solar Probe.

This image shows two massive black holes in the OJ 287 galaxy. The smaller black hole orbits the larger one, which is also surrounded by a disk of gas. When the smaller black hole crashes through the disk, it produces a flare brighter than 1 trillion stars.

This artist's concept shows the briefcase-sized Lunar Flashlight spacecraft using its near-infrared lasers to shine light into shaded polar regions on the Moon to look for water ice.
