The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope , but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy .
When our sun dies about 5 billion years from now it might look something like this glowing celestial display which was captured from 4,600 light-years away. Hubble image of a star exploding may ...
Our Sun will ultimately burn out in about 5 billion years -- here's what that might look like.
New imagery has been released from NASA’s Hubble Space Telescope, which captured a photo of a spiral galaxy more than 76 million light-years away from Earth. The galaxy known to observers as NGC ...
The Hubble length or Hubble distance is a unit of distance in cosmology, defined as cH −1 — the speed of light multiplied by the Hubble time. It is equivalent to 4,420 million parsecs or 14.4 billion light years. (The numerical value of the Hubble length in light years is, by definition, equal to that of the Hubble time in years.)
The observable universe is a spherical region of the universe consisting of all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.

NGC 2261 was imaged by the Hubble Space Telescope, and an image of the nebula was released in 1999. [6] A timelapse of NGC 2261 was taken over a period of 6 months by over 20 amateur astronomers at the Big Amateur Telescope from October 2021 – April 2022. In August 2022, the project was resumed as NGC 2261 came out from behind the Sun. [7]
