Astronomers uncover Largest known Population of Brown Dwarfs sprinkled among Newborn stars in the Orion Nebula

This image is part of a Hubble Space Telescope survey for low-mass stars, brown dwarfs, and planets in the Orion Nebula. Each symbol identifies a pair of objects, which can be seen in the symbol's center as a single dot of light. Special image processing techniques were used to separate the starlight into a pair of objects. The thicker inner circle represents the primary body, and the thinner outer circle indicates the companion. The circles are color-coded: red for a planet; orange for a brown dwarf; and yellow for a star. Located in the upper left corner is a planet-planet pair in the absence of a parent star. In the middle of the right side is a pair of brown dwarfs. The portion of the Orion Nebula measures roughly four by three light-years. Credit: NASA , ESA, and G. Strampelli (STScI)

Hubble’s Double Galaxy Gaze: Leda and NGC 4424

Some astronomical objects have endearing or quirky nicknames, inspired by mythology or their own appearance. Take, for example, the constellation of Orion (The Hunter), the Sombrero Galaxy, the Horsehead Nebula, or even the Milky Way. However, the vast majority of cosmic objects appear in astronomical catalogs and are given rather less poetic names based on the order of discovery.

Two galaxies are clearly visible in this Hubble image, the larger of which is NGC 4424. This galaxy is cataloged in the New General Catalog of Nebulae and Clusters of Stars (NGC), which was compiled in 1888...

Hubble sees Spiral in Andromeda

The Andromeda constellation should not be confused with Andromeda Galaxy. It is home to the pictured galaxy known as NGC 7640.

The Andromeda constellation should not be confused with Andromeda Galaxy. It is home to the pictured galaxy known as NGC 7640.

Andromeda constellation is 1 of the 88 modern constellations and should not be confused with our neighboring Andromeda Galaxy. The Andromeda constellation is home to the pictured galaxy known as NGC 7640. Many different classifications are used to identify galaxies by shape and structure – NGC 7640 is a barred spiral type. These are recognizable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s center. Our home galaxy, the Milky Way, is also a barred spiral galaxy...

Hubble Uncovers a Galaxy Pair coming in from the Wilderness

NASA's Hubble Space Telescope has captured the glow of new stars in these small, ancient galaxies, called Pisces A and Pisces B. The dwarf galaxies have lived in isolation for billions of years and are just now beginning to make stars. Credit: NASA, ESA, and E. Tollerud (STScI)

Hubble has uncovered 2 tiny dwarf galaxies that have wandered from a vast cosmic wilderness into a nearby “big city” packed with galaxies. After being quiescent for billions of years, they are ready to party by starting a firestorm of star birth. “These Hubble images may be snapshots of what present-day dwarf galaxies may have been like at earlier epochs,” said Erik Tollerud of the Space Telescope Science Institute in Baltimore, Maryland...
