Mammoth stars seen by Hubble







The image shows a pair of colossal stars, WR 25 and Tr16-244, located within the open cluster Trumpler 16. This cluster is embedded within the Carina Nebula, an immense cauldron of gas and dust that lies approximately 7500 light-years from Earth in the constellation of Carina, the Keel. WR 25 is the brightest, situated near the centre of the image. The neighbouring Tr16-244 is the third brightest, just to the upper left of WR 25. The second brightest, to the left of WR 25, is a low mass star located much closer to the Earth than the Carina Nebula.

Hubble studies sequences of star formation in neighbouring galaxy






The NASA/ESA Hubble Space Telescope captures the iridescent tapestry of star birth in a neighbouring galaxy in this panoramic view of glowing gas, dark dust clouds, and young, hot stars. The star-forming region, catalogued as N11B lies in the Large Magellanic Cloud (LMC), located only 160,000 light-years from Earth. With its high resolution, the Hubble Space Telescope is able to view details of star formation in the LMC as easily as ground-based telescopes are able to observe stellar formation within our own Milky Way galaxy.

Our neighbourhood galaxy the Large Magellanic Cloud (LMC) lies in the Constellation of Dorado and is sprinkled with a number of regions harbouring recent and ongoing star formation. One of these star-forming region, N11B, is shown in this Hubble image. It is a subregion within a larger area of star formation called N11. N11 is the second largest star-forming region in LMC. It is only surpassed in the size and activity by 'the king of stellar nurseries', 30 Doradus, located at the opposite side of LMC.

ACS image of NGC 5866








This is a unique NASA/ESA Hubble Space Telescope view of the disk galaxy NGC 5866 tilted nearly edge-on to our line-of-sight.

Hubble's sharp vision reveals a crisp dust lane dividing the galaxy into two halves. The image highlights the galaxy's structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo.

Some faint, wispy trails of dust can be seen meandering away from the disk of the galaxy out into the bulge and inner halo of the galaxy. The outer halo is dotted with numerous gravitationally bound clusters of nearly a million stars each, known as globular clusters. Background galaxies that are millions to billions of light-years farther away than NGC 5866 are also seen through the halo.

Wasp-39B and its parent star







A team of British and American astronomers used data from several telescopes on the ground and in space - among them the NASA/ESA Hubble Space Telescope - to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth. The analysis of the spectrum showed a large amount of water in the exoplanet's atmosphere - three times more than in Saturn's atmosphere.


WASP-39b is eight times closer to its parent star, WASP-39, than Mercury is to the Sun and it takes only four days to complete an orbit.


WASP-39b is a "hot Jupiter" extrasolar planet discovered in February 2011 by the WASP project, notable for containing a substantial amount of water in its atmosphere. WASP-39b is in the Virgo constellation, and is about 700 light-years from Earth.


As part of the NameExoWorlds campaigns at the 100th anniversary of the IAU, the planet was named Bocaprins, by Aruba. The planet is named after the beach Boca Prins in the Arikok National Park. The star WASP-39 was named Malmok.


WASP-39b has a mass of about 0.28 times that of Jupiter and a radius about 1.27 times that of Jupiter. The exoplanet orbits WASP-39, its host star, every 4 days. Hot water molecules were found in the atmosphere of WASP-39b in a 2018 study.


WASP-39b is also notable for having an extremely low density, near that of WASP-17b. While WASP-17b has a density of 0.13±0.06 g/cm3, WASP-39b has a slightly higher density of 0.18±0.04 g/cm3.
