Dazzling diamonds of Trumpler 14💎 This #hubble Space Telescope image features the magnificent star cluster -Trumpler 14. One of the largest gatherings of hot, massive and bright stars in the Milky Way, Trumpler 14 houses some of the most luminous stars in our entire galaxy ✨✨✨ . 👉Your #link to the #universe @linkobservatory👈 .

After the success of the satellite-borne Indian X-ray Astronomy Experiment (IXAE), which was launched in 1996, the Indian Space Research Organization (ISRO) approved further development for a full-fledged astronomy satellite, Astrosat, in 2004. A number of astronomy research institutions in India, and abroad have jointly built instruments for the satellite. Important areas requiring coverage include studies of astrophysical objects ranging from nearby solar system objects to distant stars and objects at cosmological distances; timing studies of variables ranging from pulsations of hot white dwarfs to those of active galactic nuclei can be conducted with Astrosat as well, with time scales ranging from milliseconds to days. Astrosat is a multi-wavelength astronomy mission on an IRS-class satellite into a near-Earth, equatorial orbit. The five instruments on board cover the visible (320–530 nm), near UV (180–300 nm), far UV (130–180 nm), soft X-ray (0.3–8 keV and 2–10 keV) and hard X-ray (3–80 keV and 10–150 keV) regions of the electromagnetic spectrum. Astrosat was successfully launched on 28 September 2015 from the Satish Dhawan Space Centre on board a PSLV-XL vehicle at 10:00AM.
Dark Side vs Light Side 🌚🌝 Which do you vibe more with? Show off your Moon love with a pair of Light or Dark Side Earrings! Or get both! Click the bio link to get your Luna goodies! 😄 Due to tidal locking we will only ever see the light (near) side of the moon from Earth but the dark (far) side has its own special characteristics too. You can see the lack of maria on the dark side as opposed to the light. Maria is the name given to the dark patches we see on the moons surface which is solidified lava: basalt seas. Theory is that as the Earth and Moon were in the early stages, the proximity to each other kept the surface of the Moon closest to us hotter, therefore collision debris hitting the moon from impacts to the earth stirred up molten lava and allowed it to reach the surface where it then solidified. The far side cooled quicker and so developed a thicker crust so impacts to that side didn’t go deep enough to break the crust to the magma. Moon photo credits: NASA
