 A 'Nebulous' Star Cluster 

In this Hubble Space Telescope view of the globular cluster Messier 28, countless multicolored stars stand out as specks in a glittering cosmic sea. But when the astronomer Charles Messier first observed the cluster in the 18th century, he mistook it for a starless nebula, or a cloud of dust and gas. Larger telescopes later revealed that Messier 28 is in fact a rich star cluster. Located nearly 18,000 light-years from Earth in the constellation Sagittarius, this cluster contains at least 50,000 stars.

Thursday, February 14, 2019: Happy Valentine's Day from space! This endearing deep-space object is the Heart Nebula, or IC 1805. Located about 7,500 light-years from Earth in the constellation Cassiopeia, this glistening cloud of cosmic dust and gas was shaped by intense radiation coming from a cluster of stars at its core. Protruding from the cusp of the heart is the Fishhead Nebula. Astrophotographer Miguel Claro captured this view from the Dark Sky Alqueva Reserve in Portugal. — Hanneke Weitering

A Galaxy With Split Personalities

(Image: © Ron Brecher)

Wednesday, February 13, 2019: Is this galaxy shaped like a spiral, or is it more of an elliptical? Astronomers have long debated the answer to this question, because it seems to have properties of both.  Known as Centaurus A, or NGC 5128, this strange galaxy is located in the southern constellation of Centaurus, and it lies somewhere between 10 and 16 million light-years away from Earth; its exact distance is another question that is still up for debate. Astrophotographer Ron Brecher created this glittering view of the galaxy using data acquired from an observatory in New South Wales, Australia. — Hanneke Weitering

The Horsehead and Flame Nebulas

Friday, February 8, 2019: Saddled up in the Orion Molecular Cloud is a horse-shaped object known as the Horsehead Nebula. This equestrian shape is a dark absorption nebula where dense clouds of dust and gas make it difficult for any light to shine through it. Also known as Barnard 33, the nebula is located about 1,500 light-years away from Earth in the Orion constellation. To its left is a bright emission nebula named NGC 2024, or the Flame Nebula. — Hanneke Weitering

A Martian River Delta

ESA/Roscosmos/CaSSIS

Thursday, February 7, 2019: A new view from the European Space Agency's ExoMars orbiter reveals an ancient river delta where water once flowed on Mars. Although liquid water has yet to be found on the Martian surface, geological features like this delta provide evidence that water played a major role in shaping the planet long ago. This 330-foot-wide (100 meters) fan-shaped feature is located in Eberswalde crater in the planet's southern hemisphere. (You can see an expanded view of the Eberswalde crater delta here.) — Hanneke Weitering

ESA/NASA/Hubble/Cramer et al.

Friday, February 1, 2019: A tail emerges from the spiral galaxy D100 in this image that combines data from the Hubble Space Telescope's Advanced Camera for Surveys and the Subaru Telescope in Hawaii. The galaxy's tail is the product of a process called "ram-pressure stripping," in which gas and plasma in the interstellar medium pulls on the galaxy as it moves through it. It's "a little like the resistance one experiences when wading through deep water," Hubble officials wrote in the image release. — Hanneke Weitering
