A light curve from NASA's James Webb Space Telescope's Near-Infrared Spectrograph (NIRSpec) shows the change in brightness from the LHS 475 star system over time as the planet transited the star on August 31, 2022. LHS 475 b is a rocky, Earth-sized exoplanet that orbits a red dwarf star roughly 41 light-years away, in the constellation Octans.

DUPLA GIRLS 2023 STAR GRAY
Here is a look back at some of the standout exoplanet discoveries of 2023. 1. JWST Identifies Heavy Elements in Distant Gas Giant's Atmosphere. The James Webb Space Telescope found that exoplanet. This list of exoplanets discovered in 2023 is a list of confirmed exoplanets that were first reported in 2023. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.

Berkeley Earth has predicted that average temperatures in 2023 will almost certainly prove to have been 1.5C higher than preindustrial levels. Although climate trends are based on decadal rather. From Mercury to Pluto (and maybe even Planet Nine), here are some of 2023's most intriguing discoveries about the planets, moons and other bodies in our solar system. Every year, we learn more. A coronal mass ejection from the sun as seen from the NOAA's GOES-16 Solar Ultraviolet Imager on March 7, 2023. Powerful Hurricane Otis approaching landfall along the west coast of Mexico on October 25, 2023, as seen in Day/Night Band imagery from the NOAA-20 satellite. Note the city lights glowing across the nation as seen from Earth orbit. It appears on evenings from Jan. 1 to Jan. 30; mornings from March 6 to Aug. 26; then evenings again from Aug. 27 to Dec. 31. Saturn is brightest in 2023 from Aug. 18 to Sept. 11. Saturn is at.

After all, vast swaths of Earth's oceans were record-warm for most of 2023, and it would take as many months for them to release that heat. An intense episode of the planet-warming El Niño. At least 579 people died in 2023 of heat-related causes in Maricopa County, where Phoenix is located, in what was the deadliest year for heat there since the county began tracking in 2003.
9 min. It's fair to say 2023 has been a difficult year in a lot of ways. In addition to devastating wars — including in Ukraine, the Gaza Strip and Sudan — 2023 also will be Earth's. The year will mark a point when humanity crossed into a new climate era — an age of 'global boiling,' as the U.N. Secretary General called it. By Chico Harlan. December 31, 2023 at 6:00 a.m.

As 2023 draws to a close, it's going out on top. "It's looking virtually certain at this point that 2023 will be the hottest year on record," says Zeke Hausfather, climate scientist at Berkeley. Updated: 3:17 PM EDT March 28, 2023 NEW YORK — Keep an eye to the sky this week for a chance to see a planetary hangout. Five planets — Mercury, Jupiter, Venus, Uranus and Mars — will line.
