Hubble Space Telescope Adds Evidence to Existence of a ‘Diamond Planet’

Using the Wide Field Camera on board the Hubble Space Telescope, a group of UK researches were able to add evidence to the theory that super-Earth 55 Cancri e — which revolves around a star 40 light years away — is, indeed, a “diamond planet.”


Back in 2012, Yale astrophysicists estimated that the carbon-based super-planet was about two times the size of Earth, eight times more dense and had a surface temperature of 3,900 degrees Fahrenheit.


The presence of carbon, combined with high density and extreme heat create the perfect conditions for creating diamonds. They speculated that one-third of the planet could be composed of pure diamond.

Taking a stab at the potential value of a diamond planet, a Forbes columnist did the math and came up with a value of $26.9 nonillion. That’s $26.9 followed by 30 zeros. Sadly, the prospects of claiming that fortune are unlikely because of the intense heat, poisonous atmosphere and inconvenient distance of 230 trillion miles.

Located in the northern constellation of Cancer, the diamond planet’s host star is clearly visible with the naked eye.


The Hubble Space Telescope, which was launched into low Earth orbit back in 1990, continues to unveil chemical curiosities throughout the universe. In the case of 55 Cancri e, the Wide Field Camera was able to detect the presence of hydrogen cyanide among the hydrogen and helium gases swirling around the planet. Hydrogen cyanide is an indicator that carbon compounds may also make up part of its atmosphere.

The findings were announced by an international team, led by scientists from University College London (UCL) in the UK. A complete report will be published in the Astrophysical Journal.

“This is a very exciting result because it’s the first time that we have been able to find the spectral fingerprints that show the gases present in the atmosphere of a super-Earth,” explained Angelos Tsiaras, a PhD student at UCL, who developed the analysis technique along with his colleagues Ingo Waldmann and Marco Rocchetto.

55 Cancri e is considered an unusual super-Earth because it orbits very close to its parent star. A year on 55 Cancri e lasts for only 18 hours.

“If the presence of hydrogen cyanide and other molecules is confirmed in a few years time by the next generation of infrared telescopes, it would support the theory that this planet is indeed carbon rich and a very exotic place,” UCL’s Jonathan Tennyson told “Although hydrogen cyanide, or prussic acid, is highly poisonous, so it is perhaps not a planet I would like to live on!”

Platinum Jewelry Illuminates the Red Carpet at Sunday Night’s 88th Academy Awards

Well before Spotlight won for Best Picture and Leonardo DiCaprio scooped up his first-ever Best Actor award for The Revenant, a bevy of Hollywood beauties — all donning stunning platinum baubles — illuminated the Red Carpet at the 88th Academy Awards. The jewelry mirrored the star-studded festivities — exciting, dramatic and frequently over-the-top.

Here are some of the highlights from Sunday night…

• Cate Blanchett, a Best Actress nominee for Carol, wore platinum by Tiffany & Co. Her ensemble included drop earrings with marquise and round diamonds ($125,000), a starfish cuff with round diamonds and a ring with a 2.30-carat round center diamond surrounded by a swirl of round diamonds ($110,000).

• Charlize Theron turned heads in a show-stopping 48.8-carat Secret Cluster Diamond Necklace by Harry Winston. The long platinum necklace was complemented by diamond cluster earrings (15.49 carats), cushion-cut diamond ring with micropavé (8.78 carats), micropavé diamond band and Queen ring with diamonds (7.44 carats). The platinum grouping was valued at $3.7 million.

• Reese Witherspoon wore an impressive suite of platinum jewelry by Tiffany & Co., which included a pair of earrings, three platinum bracelets and one platinum ring. The $1 million grouping included a ring featuring an emerald-cut 7.49-carat tsavorite with diamond accents.

• Jennifer Garner was decked out in a platinum ensemble by Neil Lane. She wore four platinum-and-diamond bracelets (150-carats, priced at $2.5 million), swirl drop earrings with diamonds and emeralds (10 carats), emerald-cut diamond ring (10 carats) and two additional platinum-and-diamond rings.

• Presenter Priyanka Chopra wore a beautiful pair of diamond drops set in platinum by Lorraine Schwartz. The earrings boasted a total weight of 50 carats and were valued at $3.2 million. She also wore three platinum rings with the following total weights and values: 22 carats ($3.4 million), 10 carats ($850,000) and 8 carats ($300,000).

• Lady Gaga, who performed the Oscar-nominated song “Til It Happens to You,” wore more than $8 million worth of platinum jewelry, including emerald-cut diamond drop earrings from designer Schwartz.
