Hubble Spies the Barred Spiral Galaxy NGC 4394

Shown in this Hubble Space Telescope image, NGC 4394 is the archetypal barred spiral galaxy, with bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. via NASA

Light Echoes

This illustration shows a star surrounded by a protoplanetary disk. A new study uses data from NASA’s Spitzer Space Telescope and four ground-based telescopes to determine the distance from a star to the inner rim of its surrounding protoplanetary disk. Researchers used a method called “photo-reverberation,” also known as “light echoes. via NASA

April 14, 1981, Landing of First Space Shuttle Mission

This was one of the central moments in my life. Space felt close, attainable. This ship became a symbol of hope for me. It’s eventual loss broke the hearts of so many. And yet that dream lives on. The rear wheels of the space shuttle orbiter Columbia touched down on Rogers dry lake at Edwards Air Force Base, NASA’s Armstrong Flight Research Center (then Dryden), California, to successfully complete a stay in space of more than two days. Astronauts John W. Young, STS-1 commander, and…

Computer-Simulated Image of a Supermassive Black Hole

Astronomers have uncovered a near-record breaking supermassive black hole in an unlikely place: in the center of a galaxy in a sparsely populated area of the universe. The observations, made by NASA’s Hubble Space Telescope and the Gemini Telescope in Hawaii, may indicate that these monster objects may be more common than once thought. via NASA

Hubble Peers Into the Heart of the Milky Way Galaxy

Peering deep into the dusty heart of our Milky Way galaxy using infrared vision, NASA’s Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Except for a few blue foreground stars, the stars are part of the Milky Way’s nuclear star cluster, the most massive and densest star cluster in our galaxy. via NASA

Simulated Atmosphere of a Hot Gas Giant

The turbulent atmosphere of a hot, gaseous planet known as HD 80606b is shown in this simulation based on data from NASA’s Spitzer Space Telescope. Spitzer measured the whole heating cycle of this planet, determining its coolest (less than 400 degrees Fahrenheit) and hottest (2,000 degrees Fahrenheit) temperatures. via NASA

Haze Layers Above Pluto

This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface. via NASA

Hubble Sees a Legion of Galaxies

Containing countless galaxies, this parallel field observation is nearly as deep as the Hubble Ultra-Deep Field. When compared to other deep fields, it will help astronomers understand how similar the universe looks in different directions. via NASA
