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 ...

Astronomers from the University of Sheffield and Pennsylvania State University have performed X-ray and optical observations of a massive star known as Melnick 39. As a result, they found that Melnick 39 is a colliding-wind ...

An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang radio telescope at the Parkes Observatory in Australia. The discovery was detailed in a research paper ...

Using NASA's Chandra X-ray observatory, astronomers have observed a massive and hot galaxy cluster known as PLCKG287.0+32.9 (or PLCKG287 for short). Results of the observational campaign, presented March 17 on the arXiv pre-print ...

Using Spektr-RG and Chandra space observatories, Chinese astronomers have investigated a nearby spiral galaxy known as NGC 7793. Results of the new study, published March 13 on the arXiv preprint server, deliver important ...

Using the Green Bank Telescope (GBT), astronomers have detected a new giant molecular cloud in the Milky Way galaxy. The newfound cloud has a size of nearly 200 light years and its mass is estimated to be some 160,000 solar ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new ultra-faint dwarf galaxy, which turned out to be gas-rich. The finding was reported in a research paper published ...

Using the Very Large Telescope Interferometer (VLTI), an international team of astronomers has observed a young Herbig Ae-type star known as T Coronae Australis. As a result, they found that the star has a companion separated ...
