Unusual glimpse of Cosmic Gems could be a breakthrough for astronomers

This artist’s impression shows two stages in the formation of a disc of gas and dust around the massive black hole at the centre of the galaxy SDSS1335+0728. The core of this galaxy lit up in 2019 and keeps brightening today — the first time we observe a massive black hole become active in real time. Credit: ESO/M. Kornmesser.

Venus likely has active volcanoes, flowing streams of lava

This is a color illustration of what exoplanet 55 Cancri e might look like. A rocky planet on the left and a portion of a much-larger star on the right. About three-quarters of the lit side of the planet is visible; the other quarter is in shadow. The surface of the planet has gray, orange, and yellow mottling. Most of the orange and yellow is in the region that is facing the star directly. The grayer portions are toward the poles and shadowed side of the planet. The edge of the disc of the planet appears to be glowing, suggesting a thin atmosphere. The star is bright orange-yellow, with a turbulent appearance similar to the Sun."
