Getting more information by measuring faster and averaging less

For signals barely larger than the noise in a system, measurement is generally a trade-off between speed and precision. Averaging over several measurements reduces the influence of noise but takes (a lot of) time. That could ...

Astronomers investigate highly variable polar V496 UMa

By analyzing data from ESA's XMM-Newton spacecraft and NASA's TESS telescope, German astronomers have inspected a highly variable polar known as V496 UMa. Results of the study, published May 20 on arXiv.org, deliver more ...

Hubble focuses on large lenticular galaxy 1023

This new NASA Hubble Space Telescope image looks at one of the nearest, massive lenticular galaxies to Earth, NGC 1023 some 36 million light-years away. Lenticular galaxies get their names from their edge-on appearance that ...

Single photon emitter takes a step closer to quantum tech

To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand. Scientists at EPFL have now designed one of these "single photon emitters" that ...

Using tiny sensors to monitor migrating monarchs

Millions of monarch butterflies migrate each fall to a specific cluster of mountain peaks in central Mexico. How exactly they navigate to their winter home, and the way they choose their path, is a topic of great interest ...

Thirteen new pulsars discovered with MeerKAT

Using the MeerKAT radio telescope, an international team of astronomers has detected 13 new pulsars in the globular cluster NGC 1851. Twelve of them turned out to be millisecond pulsars (MSPs). The discovery was reported ...
