Scientists Have Spotted the First Gamma-Ray Eclipses From 'Spider' Star Systems
In a first-of-its-kind discovery, astronomers have found seven systems in which a superdense, rapidly rotating neutron star called a pulsar is feeding on a stellar companion. These never-before seen gamma-ray eclipses are caused by the low-mass companion star moving in front of the pulsar and temporarily blocking its high-energy photons. This research could help scientists better understand how spider systems are formed, what mass marks the line between neutron stars and black holes, and how these extreme stellar remnants emit their intense radiation.
A Total Solar Eclipse is Coming Next Year - And NASA Wants Your Help to Track It
Citizen scientists can now contribute to heliophysics research by using NASA's new app, SunSketcher 2024, during the upcoming total solar eclipse in April 2024. This free app allows observers to capture images of the sun just before and after the eclipse, which will be used to record the phenomenon known as Baily's Beads. These collective observations will be compiled into an "hour-long megamovie" to enhance our understanding of the sun's shape and provide insights into its interior flows and gravitational theories.
A New Study Suggest the JWST Could Detect Life on Earth from Across the Galaxy
The James Webb Space Telescope (JWST) has shown in a new study that it could potentially detect signs of intelligent life on Earth from another star system in the Milky Way. This finding raises hopes that JWST could also identify alien civilizations on distant exoplanets. Although the results are preliminary and come with some challenges, they suggest that the telescope has the capability to detect key biosignatures and technosignatures on exoplanets within 40 to 50 light-years of Earth, opening up exciting possibilities for future discoveries.

The footage showcases thousands of long-beaked common dolphins joyfully swimming and splashing, turning the ocean into a mesmerizing spectacle of nature's beauty.
The World's Oldest Man-Made Wooden Structures Were Just Discovered in Zambia
The world's oldest man-made wooden structures, dating back half a million years, have been discovered in Zambia, predating the evolution of Homo sapiens. The well-preserved wood at the archaeological site of Kalambo Falls was shaped and joined together by early humans, challenging the notion that they were strictly nomadic and suggesting they created structures for settlement. This find sheds new light on the resourcefulness and innovation of our early ancestors, emphasizing their intelligence and ability to transform their surroundings.
