Author(s): Nataliya K. Porayko et al. (PPTA Collaboration) The existence of ultralight bosonic dark matter with mass of the order of 10^{-22} eV has been proposed to resolve certain observational puzzles. A mechanism identified by Khmelnitsky and Rubakov relates the presence of ultralight dark matter to a time-dependent variation in the times of arrival of radio pulses from pulsars. By searching data collected over more than a decade, the Parkes Pulsar Timing Array collaboration reports new and independent bounds on the density of ultralight bosonic dark matter in the vicinity of Earth.

Scientists have identified the second-fastest known pulsar, spinning at more than 42,000 revolutions per minute and located between 3,200 and 5,700 light-years away. A pulsar is the core of a massive star that exploded as a supernova. In this stellar remnant, also called a neutron star, the equivalent mass of half a million Earths is crushed into a magnetised, spinning ball no larger than Washington DC.

These rotating 'lighthouse' neutron stars begin their lives as stars between about seven and 20 times the mass of our sun. Some are found to spin hundreds of times per second, faster than the blades of a household blender, and they possess enormously strong magnetic fields.

(Phys.org)—Astronomers have recently identified a peculiar bubble-like structure associated with an energetic pulsar known as PSR J1015−5719. The newly found feature, designated G283.1−0.59, is most likely a polar wind nebula. The findings were presented June 9 in a paper published on the arXiv pre-print server.

A pulsar is a highly magnetised, rotating neutron star, which emits two beams of electromagnetic radiation which can be observed only when the beam of emission is pointing towards the Earth. Scientists believe they can use pulsars as "lighthouses" to help navigation in future interplanetary or interstellar travel.

During the 1960s, Freeman Dyson and Nikolai Kardashev captured the imaginations of people everywhere by making some radical proposals. Whereas Dyson proposed that intelligent species could eventually create megastructures to harness the energy of their stars, Kardashev offered a three-tiered classification system for intelligent species based on their ability to harness the energy of their planet, solar system and galaxy, respectively.
