Phys.org / Distant blazar OP 313 emits very high-energy gamma rays above 100 GeV
An international team of astronomers have employed one of the Large-Sized Telescopes (LSTs) at the Cherenkov Telescope Array Observatory (CTAO) to observe a distant blazar known as OP 313. Results of the observational campaign, ...
Phys.org / Pulsar wind nebula inside supernova remnant explored with Chandra
Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...
Phys.org / Triply-eclipsing triple star system discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a triply-eclipsing star system. The newfound system, designated TIC 295741342, consists of two sun-like stars in an eclipsing binary and ...
Phys.org / Astronomers discover a super-Earth orbiting a nearby red dwarf
Astronomers from Italy and Brazil have investigated a nearby red dwarf star known as Ross 318 and have discovered an exoplanet orbiting this star, which is at least six times more massive than Earth. The discovery is reported ...
Phys.org / MeerKAT discovers 15 new millisecond pulsars in a well known globular cluster
Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest ...
Phys.org / First outbursting hot subdwarf binary discovered
An international team of astronomers has utilized the Zwicky Transient Facility (ZTF) and the Transiting Exoplanet Survey Satellite (TESS) to investigate a binary system designated ZTF J0007+4804. As a result, they have found ...
Phys.org / Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years
By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the ...
Phys.org / Radio telescopes confirm 3.3-million-light-year halo in unusually quiet galaxy cluster
Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a galaxy cluster known as RXCJ0232–4420. Results of the new observations, published April 29 on the ...
Phys.org / J1152 is an unusual long-period dwarf nova with recurring eclipses, observations find
Astronomers from the South African Astronomical Observatory (SAAO) and elsewhere have conducted photometric and spectroscopic observations of a cataclysmic variable system designated SRGA J115215.0−510656. Results of the ...
Phys.org / Astronomers map lifetime of over 100,000 molecular clouds across 66 galaxies
An international team of astronomers has analyzed the data from the James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA) to investigate giant molecular clouds in nearby galaxies. The new ...
Phys.org / Optically dark gamma-ray burst reveals an unusually wide jet
Using various telescopes, an international team of astronomers has performed multi-wavelength observations of a recently identified gamma-ray burst source designated GRB 250416C. Results of the observational campaign, published ...
Phys.org / DESI-HVS1 is an old hypervelocity star ejected from the galactic center, observations suggest
Chinese astronomers report the discovery of DESI-HVS1, which may be an old metal-poor hypervelocity star of galactic center origin. The finding, based on the data from the Dark Energy Spectroscopic Instrument (DESI) and ESA's ...
Phys.org / GP Com observations sharpen picture of a rare ultracompact binary system
Using the Rozhen National Astronomical Observatory, Bulgarian astronomers have conducted optical photometric observations of an ultracompact binary known as GP Com. Results of the observational campaign, presented in the ...
Phys.org / Newly confirmed supernova remnant is one of the faintest ever detected
An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery ...
Phys.org / ALMA reveals giant molecular clouds across Needle galaxy's full disk
