By making ultraviolet light observations, Hubble has revealed some of the most energetic processes on planets, young stars and star-forming galaxies. For example, far-ultraviolet observations of Jupiter revealed unexpectedly active auroras on its poles that are hundreds of times more active than auroras on Earth. These data points have helped us learn that the auroras are caused by the Sun’s solar storms as well as particles thrown into space by its moon Io, which is known for its numerous and large volcanos.

A 120° beam angle provides the widest light spread, offering extensive coverage that’s ideal for large spaces or ambient lighting purposes. This angle is perfect for environments where even, soft lighting is required across a broad area. It’s commonly used for overhead or ceiling fixtures in spacious rooms, such as large living areas, auditoriums, or outdoor settings. The wide coverage helps reduce shadows and fills the space with a comfortable, inviting glow, making it a popular choice for general and ambient lighting.

For example, if your room is small with low ceilings, a narrower beam angle may be more effective to prevent over-lighting. For larger rooms, a wider angle will ensure even coverage. Many online calculators can quickly provide recommendations, or you can use a beam angle formula for more precise measurements.

Selecting the wrong beam angle can lead to issues such as over-lighting, creating harsh shadows, or insufficient coverage. Here are some common mistakes and tips for avoiding them:

A 90° beam angle sits between medium and wide angles, providing an even spread that’s suitable for general illumination. It’s often chosen for spaces where soft, widespread light is desired, like living rooms, offices, or areas where shadow reduction is important. The 90° angle creates a comfortable atmosphere by reducing harsh shadows and distributing light evenly across the space.

If you’ve ever pointed a blacklight – which is an ultraviolet lightbulb – at a blacklight poster, you’ve watched its inks fluoresce. The inks on the poster react to ultraviolet light by emitting visible light our eyes can see. A similar effect occurs with certain minerals, which fluoresce in vivid colors after being hit by the Sun.

Hubble has also captured ultraviolet radiation and violent stellar winds emitted by newly formed high-mass stars, which blew out an enormous cavity in the gas and dust enveloping star cluster NGC 3603. Star clusters like this one provide important clues to understanding the origin of massive star formation in the early universe.

Choosing the right beam angle is key to achieving the best lighting results. Beam angles determine how light spreads across a space, impacting the room’s ambiance and functionality. This guide will break down what beam angles mean, how to calculate them, and provide practical tips for selecting the best one for your needs, whether you’re a homeowner, interior designer, or lighting professional.

Beam angles in the 60° to 90° range are designed to provide a broader coverage of light, suitable for illuminating larger spaces. These angles distribute light more evenly across an area, making them ideal for rooms that require general, functional lighting. They are frequently used in both residential and commercial settings, such as living rooms, conference rooms, and retail spaces. These beam angles are especially useful when you need comprehensive light coverage without any intense focus, creating a comfortable and well-lit environment.

A 36° beam angle is slightly narrower, making it ideal for more focused lighting applications. This angle is frequently used in gallery lighting, where focused illumination is needed to highlight specific areas or objects. Due to its narrower spread, a 36° angle delivers more concentrated light, enhancing details and textures. It’s often used in retail displays and accent lighting where creating visual interest is key.

The observatory also has two instruments that produce ultraviolet spectra – one of Hubble’s most unique capabilities since these instruments will not be complemented or surpassed by any mission in the near future. The Cosmic Origins Spectrograph (COS) breaks ultraviolet light into components that can be studied in detail as a one-dimensional spectrum to learn about a celestial object’s temperature, chemical composition, density, and motion. The Space Telescope Imaging Spectrograph (STIS) can provide additional data about extended objects, like galaxies, as a two-dimensional spectrum.

A beam angle lighting calculator helps simplify the decision-making process by allowing you to input room dimensions and preferred lighting focus. By calculating the optimal beam angle, you can avoid common mistakes, such as choosing angles that are too wide for small spaces or too narrow for large rooms.

Telescopes above the Earth’s atmosphere with specially designed instruments, like those on the Hubble Space Telescope, are capable of gathering ultraviolet light directly. These ultraviolet observations allow us to analyze auroras on other planets, like Jupiter, learn more about Saturn’s gaseous makeup, capture fast-moving material from tightly orbiting massive stars, and identify areas of new star formation in nearby galaxies.

Ultraviolet light also helps researchers trace the vibrant glow of young, blue star clusters in galaxies like Centaurus A. Its warped shape is evidence of a past collision and merger with another galaxy, and the resulting shockwaves caused hydrogen gas clouds to compress, triggering new star formation.

Beam angle refers to the angle at which light spreads from its source, defining the area it illuminates. Narrow beam angles (e.g., 10°) focus light in a small area, ideal for accent lighting, while wider angles (e.g., 120°) provide broader coverage for general lighting needs. Choosing the correct beam angle depends on your lighting goals, the room’s size, and specific tasks. Selecting the appropriate angle enhances light distribution, efficiency, and visual impact, making it crucial for both residential and commercial spaces.

Hubble’s Wide Field Camera 3 (WFC3), which delivers some of the observatory’s spectacular images, directs light to its ultraviolet-visible light channel, which breaks down the light with filters into specific colors that are present. Once these data are sent to Earth, science visuals developers assign primary colors and reconstruct the data into a picture our eyes can clearly identify. Astronomers and citizen scientists who use specialized imaging processing software can also manipulate the raw data, assigning their own colors to elements to further study an object’s composition.

A 120° beam angle offers wide coverage, making it ideal for ambient lighting in large spaces. This wide angle floods a room with light, ensuring even illumination across the area. It’s perfect for general lighting in expansive spaces like living rooms, large offices, and outdoor areas. Because of the broad spread, a 120° beam angle is commonly used in fixtures meant for ambient or overhead lighting.

A 36° to 40° beam angle offers a medium spread of light, making it highly versatile for both general and accent lighting. This angle provides enough focus to highlight an area without creating harsh shadows or overly intense light. It’s well-suited for spaces where a balance between functional lighting and ambiance is desired. Medium beam angles are often used in residential living areas, dining spaces, and offices, where they can illuminate a broad area effectively while still offering a degree of focal emphasis.

The 120° beam angle is ideal for creating a well-lit, inviting atmosphere. It works best in large rooms or outdoor areas, where widespread illumination is beneficial. When used indoors, it can flood the area with light, making it perfect for living spaces or conference rooms. Outdoors, it can illuminate pathways, landscapes, and architectural features, providing both functionality and aesthetic appeal.

Beam angles ranging from 10° to 24° provide a very focused and narrow spread of light, making them ideal for accent lighting. These angles are perfect for drawing attention to specific details within a room, such as artwork, architectural features, or decorative items. Since the light is tightly directed, it enhances contrast and adds depth to these elements, creating a striking effect. Narrow beam angles are often used in galleries, retail displays, and any environment where highlighting particular objects or areas is a priority.

When working with LED lights, beam angles are highly versatile, allowing for greater control over the light spread. LEDs are energy-efficient and offer various beam angle options, from narrow spots to wide floodlights. Whether you need focused light for artwork or broad coverage for a workspace, LEDs can meet your specific lighting needs.

Hubble’s scientific programs are continuously refined and its instruments receive regular software updates, both of which make groundbreaking science possible. Hubble has already begun using even more advanced ultraviolet light observing modes to gather images and spectra more quickly from transient events with the goal of determining the character of objects’ fast-fading light.
