For the first time, scientists have seen neutrinos originating from the central disk of the Milky Way. Neutrinos are tiny, deeply weird particles that can zip through matter with nary a ripple. Because of their lack of interactions, they’re hard to detect—but also promising for revealing new secrets of the universe. In particular, Milky Way neutrinos may help scientists understand the origin of high-energy particles known as cosmic rays, which kick off the formation of neutrinos. And because neutrinos are particles…

Artist’s illustration of a gamma-ray burst resulting from a collapsing star, ejecting particles and radiation in a narrow jet. GRB 221009A, the most energetic gamma-ray burst ever recorded, released 1,000 times more energy than the Sun’s lifetime output. Observed with the VLT and James Webb Space Telescope, this event left scientists puzzled about gamma-ray bursts’ nature and the possible absence of an accompanying supernova.

Wildfires are a natural phenomenon that occur when dry vegetation, hot temperatures, and strong winds combine to ignite a fire. However, human activities such as careless campfires, arson, and agricultural practices have significantly increased the frequency and intensity of wildfires in many parts of the world. Wildfires have devastating consequences for local ecosystems and communities, including destruction of wildlife habitat, air pollution, and loss of property and lives.A study led by UC Irvine found that forest…

In this article, we will see how to handle the ‘error’ event that is emitted on ‘http.IncomingMessage’ in a node.js http.request.In Node.js, the ‘http.IncomingMessage‘ object is used to represent the incoming HTTP request message. This object is a readable stream, and it can emit various events such as ‘data’, ‘end’, and ‘error’. One of the events that can be emitted by this object is the ‘error’ event, which is triggered when an error occurs while processing the incoming request.The problem is that in some cases, the…

Observations from the Earth Surface Mineral Dust Source Investigation (EMIT) and other NASA science instruments will be part…

The net atmosphere-to-ocean carbon flow rates for total carbon (and hence for ΔC), anthropogenically emitted carbon CA, and for natural carbon (and hence for ΔCN). Solid lines are for the case of variable air-sea exchange, while dashed lines are for constant air-sea exchange coefficients (constant solubility and piston velocities). The light shading around lines visible for recent years indicates the half-range spread across the three versions of the…

A massive solar flare could create dazzling northern lights over parts of the US on Sunday, according to NASA. The space agency said a sun storm erupted on October 28 and sent a vast cloud of charged particles that should reach Earth on Halloween (Sunday, October 31). When these particles hit Earth's atmosphere, they will amplify the regular northern lights. Though solar fares carry harmful radiation emitting from the Sun, this one does not pass through Earth's atmosphere to physically affect humans on the ground.…
