Mapping cosmic shear to illuminate dark energy

Gravitational lensing often evokes images of a cosmic funhouse mirror: duplicated galaxies, dramatic arcs and distorted shapes. But the web-like, large-scale structure throughout the universe also bends light in a weaker, ...

Researchers develop glass sensors for the Einstein Telescope

From 2035, the Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For the telescope, researchers from Jena have manufactured highly sensitive sensors made entirely of glass for the first ...

White dwarf and red dwarf duo emit radio pulses every two hours

An international team of astronomers led by scientists from the Netherlands has shown that a white dwarf and a red dwarf orbiting each other every two hours are emitting radio pulses. Thanks to observations with several telescopes, ...

How astronomers make deep maps of the Milky Way

Have you ever wondered how astronomers manage to map out the Milky Way when it's so incredibly vast? One of the most powerful tools is something called 21 cm radiation.

NASA's PUNCH mission to revolutionize our view of solar wind

The Earth is immersed in material streaming from the sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting satellites and astronauts in space, and even affecting ground-based ...

Hubble spies a spiral that may be hiding an imposter

The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope image is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light ...

First pulsar discovered by the GCGPS survey

An international team of astronomers reports the detection of the first pulsar by the Globular Clusters GMRT Pulsar Search (GCGPS) survey. The pulsar, designated PSR J1617−2258A, was found in the globular cluster NGC 6093. ...

A spiral structure in the inner Oort cloud

We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally. Occasionally, some wayward gravitational perturbation will knock one of them a weird way and create ...

What would actual scientific study of UAPs look like?

For those who missed the memo, UFOs (unidentified flying objects) are now called UAPs (unidentified aerospace-undersea phenomena). The term UFO became so closely tied to alien spacecraft and fantastical abduction stories ...
