A binary star system containing a massive star and what is likely a black hole, which together are a source of intense X-rays, has been shown to be a smaller-scale example of some of the brightest quasars in the world. the universe. The new findings, from an international team that used NASA‘S Imaging X-ray Polarimetry … Read more
This article was reviewed according to Science fact checked peer-reviewed publication trusted source proofread OK! New observations of Jupiter’s Great Red Spot have revealed that the planet’s atmosphere above and around the infamous storm is surprisingly interesting and active. This image shows the area observed by Webb: first the location on a NIRCam image of … Read more
Science and exploration 25/06/2024 758 views 12 I like this Using NASA/ESA/CSA’s James Webb Space Telescope, scientists have observed the region above Jupiter’s iconic Great Red Spot and discovered a variety of previously unseen features. The region, previously thought to be unremarkable in nature, is home to a variety of intricate structures and activities. Jupiter’s … Read more
Scientists have directly imaged eight dim objects in Gaia’s data catalog that accompany very bright stars, including so-called “failed stars,” also known as brown dwarfs. The stars and their companions were originally identified from millions of stars in the Gaia catalog. They were considered ideal for follow-up research with the ground-based GRAVITY instrument, an advanced … Read more
Enlarge / Enhanced Juno image of Jupiter’s Great Red Spot in 2018. It is probably not the same one Cassini observed in the 17th century. The planet Jupiter is best known for its so-called Great Red Spot, a swirling vortex in the gas giant’s atmosphere that has existed since 1831. But how it originated and … Read more
Astronomers are witnessing a never-before-seen spectacle in the cosmos: the awakening of a supermassive black hole at the center of a distant galaxy. In late 2019, a team of astronomers took note of an otherwise unremarkable galaxy called SDSS1335+0728, located 300 million light-years away in the constellation Virgo. A sudden spike in the galaxy’s brightness … Read more

S-BGLS periodograms of YV2 for the star HD48948, focused on three frequency ranges (7.3, 38 and 151 d). The absolute value of log P has no meaning; instead, the relative values of log P have meaning. The signal observed at approximately 42 d in the middle panel represents the unstable activity feature. Credit: Monthly notices … Read more
