Giant planets live in the suburbs

June 4, 2021 Here’s what the biggest giant planet in our solar system, Jupiter, looks like. The Juno spacecraft captured this image during its 31st close flyby of Jupiter on December 30, 2020. The storm known as the Great Red Spot is visible on the horizon, nearly rotated out of view. Citizen scientist Tanya Oleksuik created this color-enhanced image using data from the JunoCam camera. Image via NASA. Our solar system is normal In late May 2021, astronomers released new results in a 30-year census of planetary systems beyond our own. The results show that most are arranged much like our solar system. That is, most giant exoplanets aren’t close to their parent stars, but instead live in the suburbs of their systems. That’s contrary to what astronomers thought when first discovering giant exoplanets in the 1990s. For awhile, they thought hot Jupiters – giant planets close to their stars – might be the norm. Now the California Legacy Survey, which began in the 1990s, has

Astronomers map over 100 million galaxies to crack dark matter and dark energy puzzle

Astronomers map over 100 million galaxies to crack dark matter and dark energy puzzle The Dark Energy Survey has delivered its first results providing one of the most detailed pictures of the Universe ever created. A A Reset The Dark Energy Survey (DES) is an ambitious cosmological project that aims to map hundreds of millions of galaxies. In the process, the project will detail hundreds of millions of galaxies, observe thousands of supernovae, map the cosmic web that links galaxies, all with the aim of investigating the mysterious force that is causing the Universe to expand at an accelerating rate. Using the 570-megapixel Dark Energy Camera on the National Science Foundation’s Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), Chile, the DES has observed a map of galaxy distribution and morphology that stretches 7 billion light-years and captures 1/8 of the sky over Earth.
