New double neutron star millisecond pulsar discovered

Posted by in categories: physics, space

An international team of astronomers reports the discovery of a rare double neutron star millisecond pulsar. The newfound binary pulsar, designated PSR J1325−6253, consists of two neutron stars orbiting one another every 1.8 days. The finding is detailed in a paper published April 14 on arXiv.org.

The most rapidly rotating pulsars, those with rotation periods below 30 milliseconds, are known as (MSPs). It is assumed that they are formed in when the initially more massive component turns into a neutron star that is then spun-up due to accretion of matter from the secondary star.

Some pulsars consist of two (dubbed double neutron star systems—DNS). They are one of the most important classes of objects used to test and understand numerous astrophysical and fundamental physics phenomena, including in the strong-field regime.

China Plans System to Take Out Asteroids Hurtling Toward Earth

Posted by in category: space

China plans to develop a system for monitoring asteroids that pose a threat to earth, highlighting the nation’s growing ambitions for its space program.

The country will also explore ways for taking out asteroids that endanger the planet, Wu Yanhua, deputy director of the China National Space Administration, said in a TV interview, according to the official Xinhua News Agency.

Comet C/2021 O3 might be visible in binoculars

Posted by in category: space

A comet discovered last July is fast approaching our part of the solar system and might reach binocular visibility (at least) by May 2022. It’s designated C/2021 O3 (PanSTARRS). The comet will be emerging into our western evening sky at least by early May. The comet is currently passing close to the sun, and it might not survive that passage … but if it does, get ready! Charts below.

Comet PanSTARRS will come close to the sun, closer than the planet Mercury. Its closest point, called its perihelion, will come on April 21, 2022. It’ll sweep 0.29 astronomical units (AU) from our star (1 AU = 1 average Earth-sun unit of distance). So – given that Mercury’s sunny side reaches temperatures of around 750 to 800 degrees Fahrenheit (up to about 430 degrees Celsius) – you can see that Comet C/2021 O3 (PanSTARRS) will really feel the sun’s heat.

That’s why Comet C/2021 O3 might disintegrate, as some comets do, when nearest our star.
