Hubble's Celebrates 27th Anniversary with Image of Spiral Galaxies NGC 4302 and NGC 4298

Hubble Space Telescope images of spiral galaxies NGC 4302 (left) and NGC 4298 (right) in visible and infrared light.
NASA's Hubble Space Telescope was launched on April 24, 1990. In celebration of the 27th anniversary of the launch, astronomers have taken a portrait of spiral galaxies NGC 4302 and NGC 4298. This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer.
The edge-on galaxy is called NGC 4302, and the tilted galaxy is NGC 4298. These galaxies look quite different because we see them angled at different positions on the sky. They are actually very similar in terms of their structure and contents.
This video starts with a view of the night sky as seen from the ground and zooms in onto the Virgo Cluster of galaxies. A further zoom shows the two galaxies NGC 4298 and NGC 4302 as they are seen by Hubble. The image of these two galaxies was released as part of the 27th anniversary of the NASA/ESA Hubble Space Telescope.
From our view on Earth, astronomers report an inclination of 90 degrees for NGC 4302, which is exactly edge on. NGC 4298 is tilted 70 degrees.
In NGC 4298, the telltale, pinwheel-like structure is visible, but it's not as prominent as in some other spiral galaxies. In the edge-on NGC 4302, dust in the disk is silhouetted against rich lanes of stars. Absorption by dust makes the galaxy appear darker and redder than its companion. A large blue patch appears to be a giant region of recent star formation.
Both galaxies are approximately 55 million light-years away. They reside in the constellation Coma Berenices in the Virgo Cluster of nearly 2,000 galaxies. Both were discovered in 1784 by astronomer William Herschel. Such objects were first simply called "spiral nebulas," because it wasn't known how far away they were. In the early 20th century, Edwin Hubble discovered that galaxies are other island cities of stars far outside our Milky Way.
A typical spiral galaxy has arms of young stars that wind outward from its center. The bright arms are regions of intense star formation. Such galaxies have a central bulge and are surrounded by a faint halo of stars. Many spiral galaxies also have bars that extend from the central bulge to the arms.
The edge-on NGC 4302 is about 87,000 light-years in diameter, which is about 60 percent the size of the Milky Way. It is about 110 billion solar masses, approximately one-tenth of the Milky Way's mass.
The tilted NGC 4298 is about 45,000 light-years in diameter, about one third the size of the Milky Way. At 17 billion solar masses, it is less than 2 percent of the Milky Way galaxy's 1 trillion solar masses.
The Hubble observations were taken between January 2 and January 22, 2017 with the Wide Field Camera 3 (WFC3) instrument in three visible light bands.

The heart of your home can reflect the soul of your style.
Here's how to show your kitchen in its best light.
If you have a galley-style kitchen or walkways created by an island, a single row of appropriately spaced recessed lights will complete your ambient lighting scheme. If your kitchen hugs the walls with nothing in the middle, a grid pattern will ensure even illumination across the space.
Task lighting is one of the most critical (and most often overlooked) lighting types in the kitchen. In essence, the kitchen is a work space, so make sure you have the right lighting in the right spots to enable you to work safely.
The second key to kitchen task lighting is under the cabinets. This is not a fancy add-on that can be ignored, even if you're looking to go minimal. In fact, installing undercabinet lighting is the best thing you can do to improve the functionality and environment of a kitchen. There is a wide array of systems and fixtures that can be added on to existing cabinets, as well as fully custom rail kits that integrate your lighting and power outlets into a seamless backsplash.
This is generally where the fun comes in, with decorative fixtures often fulfilling the accent role. While we're calling them out separately here, accent lighting often crosses categories and helps serve the purpose of ambient light.
Accent lighting is where we get to play a little, with fewer hard measurements and more of a design factor than ambient and task lighting. Popular places for accent lighting include above an exposed countertop like an island or peninsula, over the kitchen sink or over a table, in the case of an eat-in kitchen.

Shooting the Heart Nebula
Last night I shot into the autumn Milky Way at the Heart Nebula.
I'm currently just finishing off a month of testing the new Nikon D810a camera, a special high-end DSLR aimed specifically at astrophotographers.
I'll post a more thorough set of test shots and comparisons in a future blog, but for now here are some shots from the last couple of nights.
Above is the setup I used to shoot the image below, shot in the act of taking the image below!
The Nikon is at the focus of my much-loved TMB 92mm refractor, riding on the Astro-Physics Mach One mount. The mount is being "auto-guided" by the wonderful "just-press-one-button" SG-4 auto-guider from Santa Barbara Instruments. The scope is working at a fast f/4.4 with the help of a field flattener/reducer from Borg/AstroHutech.
I shot a set of 15 five-minute exposures at ISO 1600 and stacked, aligned and averaged them (using mean stack mode) in Photoshop. I explain the process in my workshops, but there's also a Ten Steps page at my website with my deep-sky workflow outlined.
The Heart Nebula, IC 1805, in Cassiopeia, with nebula NGC 896 at upper right and star cluster NGC 1027 at left of centre. This is a stack of 15 x 5-minute exposures with the Nikon D810a as part of testing, at ISO 1600, and with the TMB 92mm apo refractor at f/4.4 with the Borg 0.85x field flattener. Taken from home Nov 29, 2015.
The main advantage of Nikon's special "a" version of the D810 is its extended red sensitivity for a capturing just such objects in the Milky Way, nebulas which shine primarily in the deep red "H-alpha" wavelength emitted by hydrogen.
It works very well! And the D810a's 36 megapixels really do resolve better detail, something you appreciate in wide-angle shots like this one, below, of the autumn Milky Way.
It's taken with the equally superb 14-24mm f/2.8 Nikkor zoom lens. Normally, you would never use a zoom lens for such a demanding subject as stars, but the 14-24mm is stunning, matching or beating the performance of many "prime" lenses.
The Milky Way from Perseus, at left, to Cygnus, at right, with Cassiopeia (the "W") and Cepheus at centre. Dotted along the Milky Way are various red H-alpha regions of glowing hydrogen. The Andromeda Galaxy, M31, is at botton. The Double Cluster star cluster is left of centre. Deneb is the bright star at far right, while Mirfak, the brightest star in Perseus, is at far left. The Funnel Nebula, aka LeGentil 3, is the darkest dark nebula left of Deneb. This is a stack of 4 x 1-minute exposures at f/2.8 with the Nikkor 14-24mm lens wide open, and at 24mm, and with the Nikon D810a red-sensitive DSLR, at ISO 1600. Shot from home, with the camera on the iOptron Sky-Tracker.
The D810a's extended red end helps reveal the nebulas along the Milky Way. The Heart Nebula, captured in the close-up at top, is just left of centre here, left of the "W" forming Cassiopeia.
The Nikon D810a is a superb camera, with low noise, high-resolution, and features of value to astrophotographers. Kudos to Nikon for serving our market!

Both the Heart and Soul of Cassiopeia
Here are both the heart and the soul of Cassiopeia the Queen.
Two days ago I posted an image of the Soul Nebula. Now, here is the matching Heart Nebula, in a mosaic of the glorious region of the Milky Way called the Heart and Soul Nebulas located in the constellation of Cassiopeia.
They are otherwise respectively called IC 1805 and IC 1848. Amid the swirls of nebulosity are numerous clusters of stars, such as NGC 1027 just above centre. The separate patch of nebulosity at upper right is NGC 896.
I shot the frames for this 3-segment mosaic over two nights, with one segment taken from the frames that made up the previous post. Plus I shot two others to span the region of the Milky Way that is about seven degrees long, a binocular field.
Each of the 3 segments is a stack of 12 frames, with each frame a 6-minute exposure. I used the filter-modified Canon 5D MkII and shot through the TMB 92mm apo refractor at f/4.4. All processing was in Photoshop, including the mosaic assembly.
In all, it's the best image I've taken of this much-shot area of the sky. It really brings out the diversity in star colours, and sky colours, from the dusty orange-brown region at left, to the inky dark dustless region at far right.

A myopic eye can see near objects clearly but cannot see distant objects clearly. Myopia can be corrected with spectacles or contact lenses.
A hypermetropic eye needs to focus to see distant objects clearly. It will need to focus even more to see near objects clearly. Hypermetropia can be corrected with spectacles or contact lenses.
Presbyopia is a normal condition which is related to age. A presbyopic eye is one that can no longer focus sufficiently to see near objects. Presbyopia can be corrected with spectacles or contact lenses.
An astigmatic eye is not only myopic (short sighted) or hypermetropic (long sighted). It has an uneven distribution of power. A correcting lens with different powers in different alignments is necessary to provide a good focus. Astigmatism can be corrected with spectacles or contact lenses.
Diabetes can cause changes in the eye (diabetic retinopathy) which can lead to blindness. Diabetics should have their eyes examined regularly so that changes can be detected early and the necessary steps be taken to protect their eyes.
A cataract is a clouding of the lens in the eye. Most people develop some cataract as they get older. We can give you help and guidance regarding its management. It is not necessary for everyone with cataracts to have surgery however for some people the vision may become so difficult that they are happy to have their cloudy lens removed and replaced with a clear implanted one. The operation is not usually uncomfortable and it can provide a remarkable improvement in vision and quality of life.
Glaucoma is a condition that affects the health and function of the retinal nerve fibres and the optic nerve. If untreated it can lead to visual field loss (tunnel vision) and eventually blindness. It is often, but not always, associated with a raised pressure in the eye. Sophisticated glaucoma checks are an important part of an eye examination for everyone over the age of 40. If glaucoma is detected early it is much easier to treat effectively. If you do not have these checks glaucoma can progress to an advanced stage before you are even aware that you have a problem. If you have a close relative who has glaucoma you have a greater risk of developing the condition yourself.
'Floaters' may appear like black spots or pieces of cobweb floating in front of your eyes. They are very common and usually harmless. They are caused by shadows on your retina of particles floating between the lens in your eye and the retina. A sudden increase of floaters, particularly if associated with flashes of light, needs to to be checked urgently because it may be a sign of a more serious condition such as retinal detachment.
Macular degeneration causes distortions and loss of central vision. It is more common in older people when it is known as age-related macular degeneration (AMD). It is the leading cause of blindness in the UK. Most people with MD retain their peripheral (side) vision, so they can get around, but their ability to see what they look directly at can become very difficult or impossible. There are two types of MD, dry and wet. Dry MD usually causes a gradual deterioration in vision. There is currently no treatment available for dry MD but magnifying glasses and other magnifying aids can be helpful. Wet MD is caused by leaky abnormal blood vessels at the back of the eye. It can start suddenly and progress rapidly. Treatment for wet MD is available but it must be commenced very soon after the onset of symptoms.
