The Hubble Space Telescope has captured a beautiful spiral galaxy on a larger mission to chart the expansion rate of our universe.
New image of the spiral galaxy Mrk (Markarian) 1337 shows its twinkling stars shining about 120 million light-years from Earth in the constellation Virgo. NS Hubble Space Telescope UV and infrared (heat-seeking) wavelengths are preferred in this image, shown in false color.
Studying distant galaxies like these helps astronomers gain insight into the structure of our own galaxy, Galaxy, especially if it’s of the same type. “Mrk 1337 is a weakly barred spiral galaxy, which as the name suggests means spiral arms radiating from the central bar of gas and stars,” The representative of the European Space Agency wrote in an image statement.

More broadly, however, is part of a campaign to understand how rapidly the universe is expanding. The effort is led by Adam Riess, a professor of physics and astronomy at Johns Hopkins University in Baltimore, who shared the 2011 Nobel Prize in Physics for showing that the universe is accelerating as it expands.
Riess hopes to refine the rate of acceleration as the universe is expanding faster than expected, and back in 2019, we propose need new physics to really solve the problem of what is being observed versus what the models predict.
“This mismatch is growing and has now reached a level that is truly undeniable,” Riess said in a statement at that time.
More recently, he added that dispute over “Hubble constant” The universe’s expansion point is so subtle that we need to understand about dark energy, dark matter, and dark radiation, all invisible forces that affect the rate of expansion.
One way to measure constants is by graphing expansion rate between large objects like galaxies. Given that the Hubble telescope was key to the 2011 Nobel Prize, it’s no surprise that astronomers are once again turning to it as they seek to fine-tune the scale.
Hubble has struggled for several weeks to recover from the sync failure on October 23, but there is a lot of data like this to work with as an engineer. slowly bring its tools back online. Hubble was launched in 1990 and last serviced by astronauts in 2009, just before Shuttle retired and the telescope is inaccessible.
