Pune vs Vega

Informations

Pune, formerly known as Poona (Marathi: [puɳe] (listen) English: ;), is the second largest city in the Indian State of Maharashtra, after Mumbai, and the eighth most populous city in India, with an estimated population of 7.4 million as of 2020. It has been ranked as "the most livable city in India" several times.Along with the city of Pimpri Chinchwad and the three cantonment towns of Pune, Khadki and Dehu Road, Pune forms the urban core of the eponymous Pune Metropolitan Region (PMR). According to the 2011 census, the urban area has a combined population of 5.05 million while the population of the metropolitan region is estimated at 7.4 million. Situated 560 metres (1,837 feet) above sea level on the Deccan plateau on the right bank of the Mutha river, Pune is also the administrative headquarters of its namesake district. In the 18th century, the city was the seat of the Peshwas, the prime ministers of the Maratha Empire and was one of the most important political centres on the Indian subcontinent.

Pune is widely regarded as the second major "IT hub of India" and the top "automobile and manufacturing hub of India". It is known as the "Oxford of the East" with the presence of a wide range of educational institutions. India's first indigenously-run girls' school was started in Pune by Savitribai Phule along with her associate Fatima Sheikh. The city has emerged as a major educational hub in recent decades, with nearly half of the total international students in the country studying in Pune. Research institutes of information technology, education, management and training attract students and professionals from India and overseas.

Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus. Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the Sun". Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when its declination will be +86° 14′. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.

Vega is only about a tenth of the age of the Sun, but since it is 2.1 times as massive, its expected lifetime is also one tenth of that of the Sun; both stars are at present approaching the midpoint of their life expectancies. Vega has an unusually low abundance of the elements with a higher atomic number than that of helium. Vega is also a variable star that varies slightly in brightness. It is rotating rapidly with a velocity of 236 km/s at the equator. This causes the equator to bulge outward due to centrifugal effects, and, as a result, there is a variation of temperature across the star's photosphere that reaches a maximum at the poles. From Earth, Vega is observed from the direction of one of these poles.Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of collisions between objects in an orbiting debris disk, which is analogous to the Kuiper belt in the Solar System. Stars that display an infrared excess due to dust emission are termed Vega-like stars.
