Earth-Like’ Asteroid Devoured by Dead Star

The Hubble Space Telescope has recorded an intriguing event some 150 light-years from Earth.

A large asteroid was pulled into the White Dwarf star (named ‘GD 61’ by astronomers) and utterly destroyed. This is not an unusual event, as even dead stars still exhibit a very high level of gravity. However, scientists are interested because the chemical signatures left in the star’s atmosphere indicate the presence of water and a rocky surface, both considered to be key building blocks for the creation of life on our planet.

Until this event was observed, water and a rocky surface had never been found together on an object outside our solar system.

The asteroid consisted of the elements magnesium, silicon, iron and oxygen, all of which are usually found in rock minerals, but scientists believe that the abundance of oxygen indicated the heavy presence of H20.

The object was at least 90KM across and as much as 26% of that is thought to have been water. Earth is considered to be just 0.02% water.

This discovery is important because it gives scientists a vindicating glimpse of how inhabitable environments may have been formed, receiving key components (such as water) from outside sources such as meteorites.

It is thought that water first arrived on our planet by similar means and that other planets in the GD 61 system would once have received water this way as well. According to BBC News, scientists consider the presence of rocky planets in the GD system to have been “very likely”.

Scientists have observed over 1,000 planets outside our solar system, but none is thought to contain water.

Closer to home, some planets and heavenly bodies are thought to contain water. Mars is considered by many to once have had liquid water, but if this is still the case, it is a greatly reduced amount.

Elsewhere, Jupiter’s moon Europa raises a tantalizing prospect that there are oceans under its icy surface. This has led to some convincing research into the possible presence of ocean currents there. However, Europa is not alone, its fellow moons Callisto and Ganymede have also been suggested as candidates for liquid water.

In addition, Rhea (moon of Saturn), Titania (moon or Uranus), Oberon (also orbiting Uranus), Triton (moon of Neptune), Pluto (dwarf planet), Eris (dwarf planet), Sedna (possible dwarf planet) and Orcus (another possible dwarf planet) are all speculated to have oceans, some of which may be in contact with the rocky core of the respective body, which would hypothetically result in a steady stream of minerals and salts into the water – an important factor in creating life.

Saturn’s moon Enceladus has geysers, which is seen as proof of the presence of water or at least water vapours. It has even been theorized by some that Neptune contains oceans of liquid diamond.

The heavy presence of water on this asteroid is a vital clue for scientists and their understanding, not only of the cosmos, but also of how our home planet came into being.

The Different Icom Radio Connector Types Available

For a long time now, icom radios have been serving most of the consumers’ interests, offering both feature rich and compatible products. These products however need to be complemented with just the right accessories for them to work right. Here is a look at the icom 2 way radio connectors.

The Icom 2 pin right angle connector
The icom right angle connector is both convenient and flexible. It is used by most of the icom radio users, seeing it serve more people compared to the other two icom 2 way radio connectors. The icom right angle connector features a surgical grade acoustic. This ensures that you get incoming signals clearly, further enhancing efficiency. It is also made in a manner that it is easy to conceal, allowing use in environments that require discreetness. In addition to this, it also offers comfort, allowing you to wear it even for extended periods of time without feeling the itch that comes with most other connectors.

For convenience, the icom right angle connector is made in a manner that it is easy and fast to wear. It is suitable for use with the following range of icom radios: IC-F15, IC-F21, IC-F25, IC-F4GT, IC-G3GT, IC-F15s, IC-F3G, IC-F43GT, IC-F11, and the IC-F31 among others.

The icom straight pin connector
The icom straight pin connector is one of the icom 2 Way radio connectors made primarily for use with icom’s range of marine radios. Just like the icom right angle connector, the straight pin connector also offers excellent signal quality as it also comes with features like surgical grade acoustic. It is also made in a manner that it is easy to conceal, allowing for use in places where discreteness is crucial.

It further comes with a noise reducing microphone, a feature that adds to the audio quality. This allows the user to get clearer signals, and hence make better informed decisions. For convenience, it is also quite easy to put on and quite comfortable to the ears too.
If you are wondering whether your icom radio is compatible with the icom straight pin connector, you can easily verify this by checking the location of your radio’s switch. Generally, the icom range of radios compatible with this connector usually has the switch located at the place where the right angle pin connector would be connected to the radio.

The icom multi pin connector
The multi pin icom connector serves a lesser portion of the icom radio connectors as compared to the other icom 2 way radio connectors, being used mostly on the IC-F50 and the IC-F30GS. It comes with a nine pin connector making it flexible for most of the range products it is designed for. It further comes with a locking screw for effective fastening.
It also comes with surgical grade acoustic for good quality signal transmission. This ensures the user gets good quality and clear audio, ensuring efficiency. For use in sensitive areas, it is easy to conceal, and is designed in a manner that putting it on is easy and fast.

Accessories for icom 2 way radio connectors
Adjustments can be made to make these icom radio connectors work even better and with more ease on both parties’ parts. This can be made so by use of the diverse range of icom earpieces. Common accessories include soft ear plugs which make the icom connectors even more comfortable to the ears, allowing use for long periods of time. You may also connect with Bluetooth connectors for better signal transmission as well as to enable connection with other ranges of relevant devices.

Ensure you get good quality connectors
The quality of signal and audio you are bound to get on your icom connectors will depend on the quality of the connectors themselves. As such, it is crucial to ensure that you get good quality products. To ascertain the products quality and legitimacy, check to see that they are ROHS compliant, as this guarantees quality check. Also check to see that they are original icom products.

For enjoyable and assured shopping, it is recommended that you purchase these products from reputable sellers in the market. Market sentiment on icom 2 way radio forums will give you pretty good guidance.

Conclusion
Make the most out of your icom 2 way radio by using the right and good quality icom 2 way radio connectors.
