When our Sun erupts with giant explosions—such as bursts of radiation called solar flares—we know they can affect space throughout the solar system as well as near Earth. But monitoring their effects requires having observatories in many places with many perspectives, much the way weather sensors all over Earth can help us monitor what’s happening

Climate scientists studying three decades of ozone measurements from seven satellites see a positive trend in global recovery after international efforts to curb ozone-depleting substances. The part of Earth’s atmosphere with high concentrations of ozone gas protects life on Earth from the Sun’s ultraviolet radiation. However, pollutants can break down ozone, thinning this ozone layer

The excess positrons arriving at Earth must have a more exotic origin than nearby pulsars, report researchers. Their results are based on observations from the High-Altitude Water Cherenkov (HAWC) gamma-ray observatory in Mexico, which detects the shower of particles created when high-energy gamma rays smash into Earth’s atmosphere. To date, several cosmic ray detectors have

Using more than half a century of observations, Japanese astronomers have discovered that the microwaves coming from the Sun at the minimums of the past five solar cycles have been the same each time, despite large differences in the maximums of the cycles. In Japan, continuous four-frequency solar microwave observations (1, 2, 3.75 and 9.4

Southern Vietnam, hit by devastating floods produced by Typhoon “Damrey” on November 4, is bracing for yet another tropical cyclone landfall this week. Heavy rain, floods and landslides are expected over the weekend. Tropical Storm “Kirogi” formed November 17 in the South China Sea after exiting the Philippines as a tropical depression. Kirogi is the 25th named storm

This is an excerpt from Macquarie University’s Tackling Global Challenges magazine. Read the full magazine here. Oceans are fundamental to life on Earth: they regulate our climate, support countless marine species and sustain billions of people. They are also surprisingly fragile and unknown, and that’s where Macquarie University is making a splash.   “Students often

A new ice-cauldron has formed this week within the Öræfajökull volcano caldera, prompting the Icelandic Meteorological Office (IMO) to raise the aviation color code for the volcano to yellow. The last eruptive episode of this volcano started in August 1727 and ended in May 1727. A pilot flying over the area took pictures of the cauldron Friday, November

A conspiracy theory video uploaded to YouTube suggests a human figure not wearing a space suit has been captured on camera during the 1972 Apollo 17 landing. Thousands of people have viewed the video uploaded by channel Streetcap1, which is entitled “Does Astronaut’s visor reflection show a stagehand on the Apollo fake Moon set?” The

In the science of quantum communication, the challenge has always been prolonging the entangled state that the particles are in. As quantum information is carried by these entangled particles, the length of time the entanglement is sustained affects the distance that the information can travel.   Quantum communication systems do this using direct optical-fiber connections,
