#Update #Space #Telescope #Debris #Asia

A new telescope facility in the Himalayan range will now keep a watch on the overhead sky to identify transient or variable objects such as #supernovae, #gravitational lenses, #space #debris, and #asteroids. 1/n
Commissioned at Devasthal in Uttarakhand, it'll help survey the sky making it possible to observe #galaxies & other astronomical sources just by staring at the strip of sky that passes overhead. It's the first liquid mirror telescope in India & the largest in Asia. 2/n
Built by astronomers from India, Belgium and Canada, the novel instrument employs a 4m diameter rotating mirror made up of a thin film of liquid mercury to collect and focus light. It’s at an altitude of 2,450m at @ARIESNainital Devasthal observatory campus. 3/n

Two Asteroids of Over 19 Metre Diameter to Fly Past Earth This Tuesday; One to Approach Closer to #Earth Than #Moon - by @deekshith_np…

(📸: NASA/JPL-Caltech) Image
Two #asteroids with an estimated diameter between 19 and 49 metres will pass by Earth on Tuesday, September 1. While both of them are relatively large, only one of them will be very close to Earth in terms of astronomical distances.
Both asteroids, officially named #2011ES4 and #2020QG5, are classified as near-Earth objects but are not expected to pose any harm to Earth on their approach.

No other #asteroid is going to get closer to #Earth in the next decade than the one set to fly by on September 1 - by @pabsgill… Image
Many #asteroids come and go but most keep their distance from Earth as they fly past. Now one daring #asteroid is set to come closer to the planet — closer than even the #Moon on September 1.
Officially recognized as #Asteroid11ES4, the space rock will be a mere 121,000 kilometers (kms) from #Earth as it shoots past the planet next week. The #moon, on the other hand, is three times further away at 384,400 kms.

Today we’re posting asteroid content to celebrate #AsteroidDay.

In case you missed it this morning, @ESA made a programme as part of @AsteroidDay, which included @StarkeyStardust as a guest. It’s a good place to start on your @AsteroidDay journey.

Another key aspect of asteroid science is in figuring out the danger they pose to life on Earth. The poor dinosaurs owe their demise to a large space rock colliding with our planet but in this article, @monicaGrady discusses what small asteroids could do.…
Asteroids that pose a risk to Earth are 'near-Earth asteroids' - those objects that are close to our planet. This video includes Prof of Planetary and Space Science, Simon Green, speaking about them after @ajnorton3 talks about ‘A Clockwork Universe’.

To mark #AsteroidDay, we’ve got a whole day of #asteroid content ready for you. Stay on board to learn how and why we study asteroids with spacecraft, and how we protect Earth from them colliding with us. We'll even look at #SpaceMining!
#AsteroidDay was founded by astrophysicist @DrBrianMay, Astronaut Rusty Schweickart Filmmaker @GrigRichters; and B612 President Danica Remy, to encourage the public and governments to learn more about asteroids and the role they play in our Solar System.
#AsteroidDay marks the anniversary of the largest asteroid impact in recorded history, Tunguska, 1908. Such impacts are part of the reason scientists study asteroids, working on resources to search for and deflect asteroids from Earth-crossing orbits.

Moving on from #Asteroids #Exoplanets #SolarEclipse #StarSpectrum we now focus on #Satellites

Sputnik 1 was the first satellite to be launched (1957). Over 1200 active satellites are currently orbiting Earth.

Check out the LIVE Satellite Map…
Satellites come in different sizes: from the size of a lunch box to that of a small school bus.

And they are used for different purposes: Climate Monitoring, Agriculture, Telecommunications, Research.... How heavy is a satellite
Can #CitizenScientists access data from these satellites?

Yes! NASA makes available near LIVE data from many of its satellites in an interactive interface.

Allows browsing full-resolution, global satellite imagery!

Use it for your projects!

Starting from #Asteroids and #Exoplanets where we shared the Research behind our #SpaceRex project (for Asteroid Detection using #ArtificialIntelligence) and #TRAPPIST1 project (where large Resonant Chains which provide stability to this Exoplanetary system), we move to our Sun! SpaceRex project for Asteroid DetectionTrappist-1 project modeled on Harmonic Resonant Chains of the exoplanetary system
We wondered if Astronomers can find planets around stars 1000s of light years using Transit Method (dip in star's brightness because of orbiting planets) could we use this method on our parent Star- the Sun?

A unique opportunity came on 21 Aug 2017- the #TotalSolarEclipse in US Path of 21 August 2017 Total Solar Eclipse
Solar eclipses happen when Moon's shadow falls on the Earth as it passes between us and the Sun.

On 21 Aug 2017, Moon would pass between Sun and the Earth, appearing to block the Sun for almost 90 mins.

We wanted to measure dip in Sun's Brightness during this Transit Event.
