Something to look forward to: The proposed Lunar Crater Radio Telescope would not replace the full spectrum of research conducted by Earth-based radio observatories, but it does represents a vital step toward preserving and expanding humanity's ability to explore the cosmos. As the population of satellites orbiting Earth continues to grow, the Moon's far side may soon become the last sanctuary for some of astronomy's most sensitive and important investigations.

Astronomers have spotted something strange and spectacular: a mysterious object that keeps emitting pulses every 44 minutes. In a press release from Australia's Curtin University, which was part of the international team that detected the object just 15,000 light-years away in our Milky Way galaxy, astronomers explained that the find was all the more stunning because the signal is coming in the form of both X-rays and radio waves. The object, which was named ASKAP J1832-0911 after Australia's

What just happened? An international team of researchers have discovered a cosmic anomaly unlike anything previously witnessed. The object in question, located roughly 15,000 light-years away in our very own Milky Way galaxy, has been observed emitting both radio waves and X-ray radiation. The celestial body, dubbed ASKAP J1832- 0911, was initially found by astronomers using the Australian Square Kilometer Array Pathfinder (ASKAP), a radio telescope located in Australia.

Black holes are infamous for being invisible. But thanks to a new technique from the Event Horizon Telescope (EHT) team, we’re about to start seeing them in color. Astronomers have figured out a way to observe the radio sky in multiple frequencies at once, allowing them to create full-color images of supermassive black holes. The breakthrough is built on a technique called frequency phase transfer, which lets scientists correct for atmospheric interference in real time across multiple radio ban

If you look at the Milky Way through a powerful telescope, you’ll notice that close to the center of the galaxy there are elongated filaments that seem to outline its spiral shape. Scientists have a nickname for these structures: “galactic bones.” Recently, astronomers found that one of the Milky Way’s bones is “fractured,” and they believe they’ve now found a possible culprit: a neutron star that may have collided with it. According to NASA, these bones are huge elongated formations of energiz

This spark creates electromagnetic waves, with the two wires serving as transmission antennas to amplify the waves. The two wires in back are the receiving antennas, and they will produce an electric current just like with Hertz’s loop of wire.
