Astronomers from the University of California, Berkeley, and the University of Hawaii, Manoa say that based on new analysis of Kepler spacecraft data, one in five stars similar to our own sun is orbited by planets about the size of Earth, with a surface temperature that would be favorable to support life. “What this means is, when you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only 12 light-years away and can be seen with the naked eye,” said UC Berkeley graduate student Erik Petigura, who led the analysis of the Kepler data. “That is amazing,”
Petigura, along with his colleagues Geoffrey Marcy from UC Berkeley and Andrew Howard from the University of Hawaii, has had their analysis published online in the journal Proceedings of the National Academy of Sciences. The researchers point out that just because an exoplanet is Earth-sized or is in an Earth-sized orbit does not automatically mean that it can support life, even if their orbits are within a star’s habitable zone, where temperatures are not too hot or too cold.
“Some may have thick atmospheres, making it so hot at the surface that DNA-like molecules would not survive,” Marcy said. “Others may have rocky surfaces that could harbor liquid water suitable for living organisms. We don’t know what range of planet types and their environments are suitable for life.” Last week Marcy, Howard, and their colleagues made news when they announced that they found Kepler-78b, an Earth-sized exoplanet with the same density and a core made up of the same mixture of rock and iron as our own planet.
But since it orbits so close to its star, this newly-discovered rocky planet has a blazing surface temperature of about 2,200 degrees Kelvin, which is far too hot to support life as we know it. The team focused on 42,000 stars that are like the sun or slightly cooler and smaller. Among those stars, the researchers said they found 603 candidate planets orbiting them. Of these candidate exoplanets, only 10 were Earth-sized, meaning that they were about one to two times the diameter of Earth and orbiting their star at a distance that would provide life-supporting temperatures.
To find how many other Earth-sized planets residing in habitable zones they missed in their search, the researchers put planet-finding algorithms devised by Petigura through a number of tests. In these tests, Petigura actually threw in some fake planets into the actual Kepler data to find out which planets his software could detect and which it couldn’t.
“What we’re doing is taking a census of extrasolar planets, but we can’t knock on every door. Only after injecting these fake planets and measuring how many we actually found, could we really pin down the number of real planets that we missed,” Petigura said. Taking several factors into consideration, such as these missing planets, and that only a small number of Earth-like exoplanets are situated in such a way that they can be seen transiting in front of their host stars from Earth, the team estimated that 22 percent of all sun-like stars in the galaxy have Earth-size planets in their habitable zones.
“Until now, no one knew exactly how common potentially habitable planets were around Sun-like stars in the galaxy,” said Marcy. Although they found all of the possibly habitable planets circling around cooler K stars, or Orange Dwarfs, which are somewhat smaller than our sun, the researchers said that the results of their analysis could also be inferred to G stars like the sun.
The researchers speculated that if the Kepler spacecraft hadn’t been crippled by technical malfunctions this past spring and was able to fully continue its research mission, it would have been able to gather enough data to directly detect some Earth-size planets in the habitable zones of G-type stars. This new, more thorough analysis of Kepler data made by the researchers shows that “nature makes about as many planets in hospitable orbits as in close-in orbits,” said Howard. (VOA/JC)

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment. While everyone is making their big fat Indian wedding dreams come true, they are also adding their carbon footprint and undue energy consumption. Modern couples are now looking for ways to have a wedding with a sustainably conscious mindset. It's become about incorporating less waste, locally sourced and seasonal food, natural materials over the use of plastic. Mindful wedding planning and decor includes the use of recycled paper and goods along with eco-friendly venue needs. Check out this quick guide to achieve a sustainably conscious wedding without compromising on luxury:
Choose locally sourced material to uplift artisans
Sustainable can be luxurious too, incorporate some native flavour into the decor and theme. With the use of locally sourced materials and local artisans coming into play, the wedding instantly becomes sustainable. Include the work of local vendors ensure minimal packaging requirements, thus saving on unnecessary plastic and lamination. It also decreases the need for transporting elements from other cities and hence lowers the carbon footprint. For instance, at one of our weddings, we made use of sand art for a setup in Jodhpur. This helped promote local work while also being environmentally friendly with zero wastage of other materials. In another instance from Rajasthan, the traditional glass-blown technique was used to build decor items while giving a cultural touch to the destination wedding.

Say yes to recycling
One should be mindful and avoid the use of plastic and other non-recyclable materials in decor wherever possible. It can be a small step such as making a conscious switch from plastic water bottles to copper jugs or glass bottles. Also use artificial floral decor thus minimising the wastage produced from real flowers. This recyclable decor is then donated to various NGOs, further ensuring sustainable use of resources. Such steps, however small they might be, keep the environment free from the release of any additional carbon footprint.

Go for zero-waste wedding decor
Make use of fabric as it enhances the elegance of the wedding while being sustainable. Include vibrant colours apt to the theme of the wedding and bring in bright sprightliness with breathable fabrics. Ensure to include LED lights for lighting. They can be incorporated as string lights or be used on passageways with innovative decor items. They also help conserve energy and bring in soulful energy for nighttime decor. Choose virtual invitations, keeping up with the digital times. Make a conscious choice of plated dinner menus rather than a buffet as they allow less wastage of food and ensure enough food for guests in attendance.

Include Sustainable Gifting
Gift sustainable wedding favours -- gifts that grow. Offering a plant or a succulent, is a great idea. One can also gift recycled organic fabrics and cutlery or zero-waste kitchen and bathroom essentials to use in their homes as some distinct gifting options.

Acting in the best interest of the environment and the society, Theme Weavers Designs has started a social cause, Weaving Hope, where a part of their earnings along with food and decor are donated to social communities. Royal Rendezvous, is an event started by us to put India on the Global Map, inviting international wedding planners to India to experience the rich culture and heritage, also employing and displaying the work of local artisans to this international audience.
By applying the values of sustainability, you can reduce the energy consumed and the resources used as much as possible. Go ahead and have a luxurious zero-waste wedding and navigate into the world of green living! (IANS/ MBI)

Of the 16,43,879 people who were inoculated, a total of 10,85,097 received their first dose and 5,58,782 their second dose of vaccine, the statement said, A total of 9,66,568 people in the age group of 18-44 were vaccinated on Sunday and vaccines were administered on 5,02,578 people aged between 45- 59 in the mega vaccine camps.
State health minister Ma Subramanian, who inaugurated the vaccination at Pollachi, also visited the centres in six districts -- Coimbatore, Erode, Namakkal, Tiruppur, Dharmapuri and Salem. The state government, according to the health minister, is to receive the next allotment of vaccines on September 21. Minister while speaking to IANS said, "We will be receiving the next allotment of vaccines on September 21 itself and we will resume vaccinations immediately. The state has already touched one crore vaccine-mark in the month of September till date." (IANS/MBI)
