Hubble captures an elegant spiral galaxy 60 million light-years away

This week’s image from the Hubble Space Telescope shows the spiral galaxy NGC 4571, located 60 million light-years away in the constellation of Coma Berenices, and was captured using Hubble’s Wide Field Camera 3 instrument.

This cosmic portrait – captured with the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 – shows a stunning view of the spiral galaxy NGC 4571, which lies approximately 60 million light-years from Earth in the constellation Coma Berenices. This constellation – whose name translates as Bernice’s Hair – was named after an Egyptian queen who lived more than 2,200 years ago.

“This image comes from a large program of observations designed to produce a treasure trove of combined observations from two great observatories: Hubble and the Atacama Large Millimeter/submillimeter Array (ALMA),” Hubble scientists write. “ALMA is a vast telescope consisting of 66 high-precision antennas high in the Chilean Andes, which together observe at wavelengths between infrared and radio waves. This allows ALMA to detect the clouds of cool interstellar dust which give rise to new stars.”

The combination of Hubble and ALMA observations makes a great pairing for observing targets using different wavelengths. “Hubble’s razor-sharp observations at ultraviolet wavelengths, meanwhile, allow astronomers to pinpoint the location of hot, luminous, newly formed stars,” the Hubble scientists continue. “Together, the ALMA and Hubble observations provide a vital repository of data to astronomers studying star formation, as well as laying the groundwork for future science with the NASA/ESA/CSA James Webb Space Telescope.”

Like Hubble, ALMA has been used to study a variety of targets, from distant objects like a series of planets in various stages of formation to those in our own solar system like Jupiter and its complex atmosphere. The array even contributed to large-scale projects like the discovery of a trove of ancient, massive galaxies which gave clues to the earliest stages of the universe.

The galaxy NCG 4571 was imaged as part of the PHANGS-HST project (Physics at High Angular resolution in Nearby GalaxieS with the Hubble Space Telescope) between Hubble and ALMA. This survey aims to learn about how young stars form from clouds of gas by looking at nearby galaxies. A previous Hubble image of the week, of the beautiful spiral galaxy NCG 2835, was part of this same project.

Hubble sees the dramatic collision of NASA’s DART spacecraft and an asteroid
These three panels capture the breakup of the asteroid Dimorphos when it was deliberately hit by NASA's 1,200-pound Double Asteroid Redirection Test (DART) mission spacecraft on September 26, 2022. Hubble Space Telescope had a ringside view of the space demolition derby.

Last year NASA tested out a new method for defending the planet from incoming objects by crashing a spacecraft into an asteroid. Recently, further analysis of data from the impact has shown more about what occurred during and after the impact, and how effective it was at changing the orbit of the asteroid.

The Hubble Space Telescope captured a series of images showing the aftermath of the impact, which have been put together into a video showing the bright flash of the impact and the emerging plume of material sent up from the asteroid:

An enormous galaxy cluster warps spacetime in this Hubble image
A massive galaxy cluster in the constellation Cetus dominates the centre of this image from the NASA/ESA Hubble Space Telescope. This image is populated with a serene collection of elliptical and spiral galaxies, but galaxies surrounding the central cluster — which is named SPT-CL J0019-2026 — appear stretched into bright arcs, as if distorted by a gargantuan magnifying glass. This cosmic contortion is called gravitational lensing, and it occurs when a massive object like a galaxy cluster has a sufficiently powerful gravitational field to distort and magnify the light from background objects.

Every week, scientists using the Hubble Space Telescope share an image from this beloved piece of space technology, and this week's image shows a vital astronomical phenomenon in action. While space telescopes can observe very far-off objects if they are bright enough, there is still a lot of the universe that is too far away to observe -- which is why researchers make use of a natural occurrence called gravitational lensing.

Gravitational lensing happens when an object like a galaxy or galaxy cluster has so much mass that it noticeably warps spacetime. Everything with mass bends spacetime somewhat, but usually this effect is so small as to be effectively invisible. But when the object is something with as much mass as a large galaxy or even a collection of galaxies, then this warping can be significant enough for us to observe it.

Three galaxies are in the process of merging in this Hubble image
A spectacular trio of merging galaxies in the constellation Boötes takes center stage in this image from the NASA/ESA Hubble Space Telescope. These three galaxies are set on a collision course and will eventually merge into a single larger galaxy, distorting one another’s spiral structure through mutual gravitational interaction in the process. An unrelated foreground galaxy appears to float serenely near this scene, and the smudged shapes of much more distant galaxies are visible in the background.

This week's image from the Hubble Space Telescope shows a dramatic collision of three different galaxies. The trio, located in the Boötes constellation, are in the process of merging and will eventually form one single large galaxy.
