Using the Australian Square Kilometer Array Pathfinder (ASKAP), astronomers have discovered 15 new giant radio galaxies with physical sizes exceeding 3 million light years. The finding was reported in a research paper published ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers have detected a new sub-Neptune exoplanet orbiting a bright G-type star. The newfound alien world, designated TOI-3493 b is more ...

Using the Australia Telescope Compact Array (ATCA) and Parkes 64-m telescope, an international team of astronomers has performed a radio continuum study of MC SNR J0519–6902—a supernova remnant in the Large Magellanic Cloud ...

By analyzing the available observational data, astronomers from the Tribhuvan University in Nepal and elsewhere have investigated the properties of a compact dwarf galaxy designated SDSS J134313.15+364457.5 (or J1343+3644 ...

Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have observed an X-ray binary system designated SXP 138. Results of the NuSTAR observations, published March 26 on thearXiv pre-print server, ...

Astronomers from Swinburne University in Australia and elsewhere have employed the Keck II telescope to investigate the globular cluster system of an ultra-diffuse galaxy designated NGC5846_UDG1. Results of the observations, ...

An international team of astronomers has performed optical photometric, polarimetric and spectroscopic observations of a cataclysmic variable system known as ASASSN–14dx. Results of the new observations, published April 9 ...

Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a nearby star known as GI 410. The newfound alien world was classified as a sub-Neptune exoplanet with ...

Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have performed X-ray observations of an X-ray binary designated 4U 1907+09. Results of the observational campaign, published April 3 on the arXiv ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a planetary nebula designated Messier 57 (also known as NGC 6720), dubbed the Ring Nebula. As a result, they found that the central ...

Using ESA's XMM-Newton satellite, Italian astronomers have observed a Galactic X-ray binary system known as 4U 0728-25. Results of the new observations, presented in a research paper published March 28 on the arXiv preprint ...

Using the 10.4-m Gran Telescopio Canarias (GTC), European astronomers have detected methane in the atmosphere of WISEA J181006.18−101000.5—the closest T dwarf to Earth. The finding was reported in a research paper published ...

Astronomers from the Czech Republic and Argentina have employed the Gemini South telescope to observe a yellow supergiant star designated HD 144812. The observations found that HD 144812 is a rare post-red supergiant orbited ...

Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new warm Jupiter exoplanet located more than 1,000 light years away. The newfound alien world, designated TOI-2005 ...

Using the Very Long Baseline Array (VLBA), European astronomers have carried out multi-wavelength radio observations of a radio galaxy designated 3C 111. Results of the observational campaign, published March 24 on the arXiv ...
