5 Largest Star Constellations Visible from the UK

What beginning stargazers need to see and learn from the night sky

If you are new to the stargazing hobby, you are likely still in the process of “learning” the sky, and how to find your way around. While there are many ways of learning to find objects to view, one of the easiest is to learn to identify the constellations. Many constellations contain spectacular deep sky objects within their borders, so if you know where a particular constellation is at any given time, you can drastically reduce the time you spent looking for an object.

That said though, many constellations look nothing like the mythological creatures they are said to represent, and even some professional astronomers have some difficulty in identifying some of the more obscure constellations. Moreover, not all constellations are always visible from any spot on the globe, but observers in the UK are fortunate in that the five biggest constellations out of the 88 recognized constellations are all visible from within the borders of the United Kingdom. Let us look at each of these constellations in a little more detail.

Hydra, the Water Snake

Hydra is the largest of all the constellations, and it takes up 3.15% of the sky, which works out to 1 303 square degrees between latitudes +54° and -83° in the southern sky. Although the constellation is located in the southern sky, it is fully visible from the UK along with some others that also fall in the southern sky. The best time to see the Water Snake stretched out over its full length (102.5 degrees) is at around 9 PM (Local Time) during April.

All told, Hydra has 238 stars, of which Alphard (Alpha Hydrae) is the most luminous with an apparent visual magnitude of 1.98. The constellation’s star count includes 18 stars that host 23 planets between them. Notable deep sky objects in Hydra include the open cluster Messier 48, the globular cluster M68, the Southern Pinwheel Galaxy (M83), the Hydra Cluster of galaxies, Tombaugh’s Globular Cluster (NGC 5694), the Ghost of Jupiter nebula, and the spiral galaxy ESO 510-G13.

Hydra is bordered by the constellations Antlia, Cancer, Canis Minor, Centaurus, Corvus, Crater, Leo, Libra, Lupus, Monoceros, Puppis, Pyxis, Sextans and Virgo, which it makes it easy to identify, since some of the bordering constellations are very prominent.

Virgo, the Virgin

Virgo is one of the 12 zodiac constellations first catalogued by the Greek astronomer Ptolemy in the 2nd century. Occupying an area of 1 294 square degrees, between latitudes +80° and -80° in the southern hemisphere, it is the second largest of all the constellations. Like Hydra, Virgo is visible from the UK because it lies close to the ecliptic. The best time to view Virgo is at about 9 PM (Local Time) during May.

Virgo contains the autumn equinox point, a point in the sky that marks the intersection of the ecliptic and the celestial equator. The opposite point is in the constellation Pisces; the two points mark the beginning of the northern autumn, and the southern spring respectively when the Sun crosses these positions.

Notable deep sky objects in Virgo include the very bright galaxies M49, M58, M59, M60, M87, as well as the famous Sombrero Galaxy, M104. Virgo also has 26 stars that host 33 planets between them, more than any other constellation. Constellations that border on Virgo are Boötes, Coma Berenices, Corvus, Crater, Hydra, Leo, Libra and Serpens Caput.

Ursa Major, the Big Bear

Ursa Major is the largest of the northern constellations, and the third largest overall, taking up an area of 1 280 square degrees between latitudes +90° and -30° in the northern sky. The Bear is perhaps best known for the famous Plough, or Big Dipper asterism (as it is known in the USA), it contains. Along with the constellations Orion and the Southern Cross, Ursa Major has a history dating back several thousand years, and it has been known in every major culture of the world, albeit under different names at different times. Ursa Major is best seen at about 9 PM (Local Time) during April.

All told, Ursa Major has 209 stars of which 18 host 24 planets between them. Apart from lots of planets, Ursa major also contains some spectacular deep sky objects, some of which are easy targets for amateur equipment. Some notable objects include the Pinwheel Galaxy (M101), Bode’s Galaxy, the Cigar Galaxy, and the Owl Nebula.

Constellations bordering on Ursa Major are Boötes, Camelopardalis, Canes Venatici, Coma Berenices, Draco, Leo, Leo Minor and Lynx.

Cetus, the Whale

Cetus is located in a region of the sky known as “Water”, along with some other constellations whose names are connected to water in some way. The constellation takes up an area of 1 231 square degrees between latitudes +70° and -90° of the southern sky. The Whale is best seen at about 9 PM (Local Time) during November.

All told, the constellation contains 189 stars, 21 of which host 27 planets between them. Apart for stars like Deneb Kaitos (Beta Ceti), Menkar (Alpha Ceti), and Mira (Omicron Ceti) that are all famous for various reasons, the constellation also includes some notable deep sky objects, such as M77, a barred spiral galaxy located about 50 million light years away, and the “Pac-Man Nebula” that is named for the arcade game character, because it appears to be slurping up the stars in the surrounding star field.

Constellations that border on Cetus are Aquarius, Aries, Eridanus, Fornax, Pisces, Sculptor, and Taurus.

Hercules, the (Roman) Hero

Although Hercules was catalogued by the Greek astronomer Ptolemy in the 2nd century, it’s history dates back to ancient Sumerian times, when it was associated with the hero Gilgamesh in an epic tale that resembles some stories from the Old Testament.

Being the fifth largest constellation in the sky, Hercules takes up an area of 1 225 square degrees between latitudes +90° and -50° in the northern sky. All told, the constellation contains 245 stars, 16 of which host 19 planets between them. However, despite the constellations’ large star count, it does not contain any first magnitude stars, but the constellation is relatively easy find. Look for the prominent Keystone asterism that is made up of Pi, Eta, Zeta, and Epsilon Herculis, the four brightest stars in the constellation.

Some notable deep sky objects in Hercules include M13, a large globular star cluster located on one side of the Keystone, M92, which at about 14 billion years old is arguably the oldest star cluster known, the Hercules Cluster of galaxies (NGC 6210), and Abell 2199, a large galaxy cluster. Particularly noteworthy is the fact that Hercules contains the Hercules–Corona Borealis Great Wall, the largest known superstructure in the Universe. This conglomeration of galaxy clusters stretches over 10 billion light years in length, 7.2 billion light years in breadth, and 1 billion light years in depth.

5 Strategies That Guarantee A Smart Landscape Design

The fact that landscape design is a booming industry at the present moment does not state that you cannot take part of it in your home. In fact, there are a lot of landscape design DIY projects you can engage in and give your home or work area a new meaning.

But how to know if your project is going to fit in the traditional view of landscape design? We are listing a checklist of all the most important aspects for your overall planning and development.

1. Plan For Equipment Access

One of the first and foremost rules you need to consider when working under the premise of landscape design – is the importance of anticipating future access. Whether it is mowers or stump grinders, future building projects such as a porch or patio, you will face an additional project or repair that requires some machinery to get into your backyard. Therefore, access is important.

2. Start With The Focal Points

A focal point is what makes your project look unique – and although we are used to looking at a specimen tree or statue as a focal point, this is not a strict rule to follow. Speaking of rules, the best one we can give is the ability to find something that is slightly to very different from the rest of the area – whether in form, texture or color.

3. Keep The Curves In Check

Including curves to your garden project will improve its sense of style, uniqueness and look – as long as it is not overdone. The best way to go with is with long and subtle curves that do not take you far out of the way of your destination.

4. Add Movement To Your Project

Landscape design is a form of art – but not quite similar to paintings. They are fine for hanging on a wall, but a garden needs some movement to add life and interest – which is why you may want to consider ornamental grasses swaying in the breeze.

5. Keep The Spacing In Mind

A lot of landscape designers focus too much on plants – and less on space. In reality, space is what you need for your garden and home, and the main benefit you will get from your project. Also, proper spacing allows better air circulation and prevents any fungal and insect problems.

In the end, you should know that landscape design should not follow strict rules. What it should follow is your own gardening mantra and the way you see plants. Only with this as a ‘rule’, you will see its value and put your mind and creativity to practice. In the end, landscape design is all about giving your home the holistic approach in needs, but also a great way to save money and invest in years of enjoyment.

Invest In Your Business with a Professional Office Fit Out

Increase Productivity & Profit

When designing an office there are many things to take into consideration. The design and layout of an office has a huge impact on the performance of employees. For starters, if employees feel that they are too overcrowded in an office, and if the office environment is not nicely decorated and clean, they are naturally going to be demotivated.

Their efficiency and performance will thus suffer considerably as a result, and this will have an impact on overall costs for your firm. Therefore an office fit out or refurbishment does not have to be considered as a waste of money at all. It should on the other hand be considered as a form of investment, because if your employees are feeling happy they are going to be more productive and efficient.

This has been seen in countless commercial establishments and offices. In fact throughout the years, businesses who have invested in interior improvements whether large or small, have shown to have far higher productivity rates amongst staff.

Laying the groundwork

A good, reputable interior fit out firm will always start off with a thorough evaluation of the office space available, as well as a consultation with the business owner. They need to be well aware of the operations of the firm as well as the number of employees that will be working in the office. In such a way, they will be better able to come up with office fit out designs that will encourage efficiency during the business operations.

They should take into account various things which most business owners will have left unnoticed. For instance, they will try to make use of natural light as much as possible. They will see to the electrical connections that are required beforehand, as well as other installations, plumbing works and numerous areas that require a qualified engineer to install or maintain, which helps the office run more efficiently.

Sticking to timelines

Another aspect they should place a great deal of importance on is the completion time for the office fit out. They should understand that while the fit out is being carried out, your business cannot operate normally, and at times, not at all!

Therefore, they need to make sure that the completion date is adhered to, and that they stick to it at all costs. They will also do their best to minimize any inconvenience the work in progress can cause. When formulating the office fit out project plan, they should be responsible for coordinating the job times properly one after the other and also be responsible for contacting and arranging the necessary contractors and service providers for their respective jobs or tasks in order to avoid any unnecessary delays.

So if you are considering an office fit out, make sure that you are going to hire someone who really knows what to do and is fully certified and qualified. Choose a firm who prides themselves that they are experts in office fit out, and we guarantee that you won’t regret hiring them.
