meanwhile NASA's Dawn mission is a success, it has started circling around Ceres after spending some days with Vesta, and became a satellite to the dwarf planet Ceres between Mars and Jupi. it looks quite amazing how it entered into the orbit, reverse gravitational capture oO.

and for the first time in history humankind detected those two bright spots on Ceres, and left peoplekind guessing what these actually are ?

such small piece of astronomical object is unlikely to have such hot molten core, probably what they are saying is the case, internal icy stuff/cryovolcano got exposed due to asteroid impact or some radio active deposits from also asteroid impacts.
to say, Ceres is very much black like slate, and those bright sponts even though look so bright in picture, should not be much brighter than just being dull, probably just higher reflective materials.

Yes, it is smaller compared to other heavenly bodies. But it is still pretty large by asteroid standards.

Guys can you suggest me a telescope

I wanted to buy a Telescope and had kept postponing. Now PayTM has a offer going on, about 40% off, which makes it a sweet deal.

Looking for a beginner telescope. Can anyone suggest me something? It's mostly for astronomical viewing ( but terrestrial view wouldn't hurt. ) Don't need a smaller one or compact, it can be big as much it can.

Budget - 9-10K (so that post offer its 5-6K)

Mystery of Ceres Lights solved. They are saying it was sun light reflecting on ice. Mostly. There were more of it.

Philae, the comet lander that was carried and deployed by the Rosetta probe has awoken 7 months after landing and makes contact with Earth.
