The Image by Hubble Telescope Speaks

A new Hubble Space Telescope photograph of a spiral galaxy shows glistening stars, including a few in the foreground.

The telescope photographed UGC 11537, a galaxy in the constellation Aquila that is 230 million light-years away. The galaxy is over ten times the distance from Earth’s stunning Andromeda Galaxy (M31), which can only be seen with the naked eye.

As UGC 11537 sits on the Milky Way’s plane, where the majority of our galaxy’s stars dwell, two starry interlopers from closer to home, crept into the photograph. According to research conducted by the European Space Agency, it was announced in late November.

“The spikes that encircle these stars are diffraction spikes, which are image errors. They’re caused by starlight colliding with the structure that holds Hubble’s secondary mirror in place “In its description, the ESA noted.

About the Spiral Galaxy Image

The spiral galaxy was discovered as part of a bigger search for supermassive black holes at the center of these star systems. Hubble is being used in the investigation, as well as images from ground-based observatories. It will determine the mass and velocity of stars in galaxies such as UGC 11537. According to ESA, these measures will aid in estimating the mass of supermassive black holes.

Data from Hubble’s Wide Field Camera 3 was used to create the image. On Oct. 26, the camera and other Hubble instruments were disabled due to a synchronization issue, forcing the 31-year-old observatory into safe mode. Engineers rearranged the observatory’s timetable and meticulously reconnected each equipment, finishing the operation on Monday (Dec. 6).

After years of technical and financing delays, the James Webb Space Telescope, Hubble’s successor, is set to launch into space on Dec. 22. Hubble will most likely continue to operate long into the 2020s. According to NASA, the two observatories will collaborate on at least some investigations in the future years.
