NEW DELHI: One year passes in the blink of an eye in terms of the age of our universe, but 2017 has made significant contributions towards unravelling the deep mysteries hidden in its vast expanse, giving the search for alien life a big boost.
From the first observations of a merger between two faraway neutron stars to stunning discoveries of a number of exoplanets in the habitable zone of a nearby star and the continued march of China as a serious space player, this year has had plenty of memorable developments to excite scientists and the public at large.
Marked as the “breakthrough of the year” by the journal Science, the merger of the two neutron stars 130 million light years away generated tiny ripples in the fabric of space-time called gravitational waves.
The first detection of gravitational waves two years ago has already brought scientists the 2017 Nobel Prize in Physics, but sensing the space-time ripples after the merger of the neutron stars marked the first-ever detection of gravitational waves as well as light produced and emitted during the same cosmic event, a phenomenon that scientists like to describe as hearing and seeing the violent universe.
While the observation of this collision provides scientists clues on how heavy elements like gold and platinum are produced in our cosmos, and advances understanding of the universe in myriad other ways, the discovery of several Earth-sized planets orbiting stars outside our solar system has whetted the thirst for finding signs of life in worlds other than our home planet.
In February, NASA’s Spitzer Space Telescope revealed the first known system of seven Earth-sized planets around a single star — the TRAPPIST-1 star — an ultra-cool dwarf located at about 40 light-years from Earth.
The researchers determined that three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
The discovery set a new record for maximum number of habitable-zone planets found around a single star outside our solar system.
In yet another first for the year, scientists spotted an “interstellar object” entering our solar system.
The discovery was made on October 19 by the University of Hawaii’s Pan-STARRS 1 telescope during the course of its nightly search for near-Earth objects for NASA.
The discovery, termed “historic” by the US space agency, revealed the interstellar interloper to be a rocky, cigar-shaped object with a ratio of length to width unlike any asteroid or comet observed in our solar system.
The team from the Pan-STARRS observatory has chosen the name “Oumuamua” for their discovery. Of Hawaiian origin, the name means a messenger from afar arriving first.
In 2017, NASA made progress in the preparations to send astronauts to Mars and it became clear that the agency would have to make plans for returning astronauts to the Moon in preparation for human missions to the Red Planet and other destinations of our solar system.
The year also marks the end of Cassini’s 13-year tour of Saturn as the spacecraft made a fateful plunge into the atmosphere of the ringed planet on September 15. The mission is often credited for transforming our understanding of ocean worlds, where life may potentially exist beyond Earth.
In April, NASA said that its Cassini spacecraft discovered hydrogen in the plume of gas and icy particles spraying from Saturn’s moon Enceladus. The discovery means the small, icy moon — which has a global ocean under its surface — has a source of chemical energy that life can feed on.
And even as the spacecraft is gone, scientists hope that its enormous collection of data about Saturn — the giant planet, its magnetosphere, rings and moons — will continue to yield new discoveries for decades to come.
The year also marks some giant strides taken by China to emerge as a formidable space power. One of its satellites, which was sent to the skies to look for evidence of the annihilation or decay of dark matter particles in space, detected for the first time unexpected and mysterious signals in its measurement of high-energy cosmic rays, bringing scientists closer to proving the existence of the invisible matter.
Prior to the brutal second wave of the pandemic, Prime Minister Narendra Modi had cautioned civil services probationers against developing the despised "babu mindset". He gave the invaluable piece of advice while addressing civil services probies at the well-known Lal Bahadur Shastri National Academy of Administration in Mussoorie via video-conferencing. He also outlined the keystone mantra of "minimum government and maximum governance".
With the recent collapse of the under-construction flyover in Bandra Kurla Complex which injured 14 labourers, it seems like the Brihanmumbai Municipal Corporation (BMC) has got the PM's keystone mantra all wrong. The recent flyover collapse isn't an isolated incident, in fact, a month ago a similarly bemusing incident took place in the eastern part of the suburbs.
On 1st August 2021, the honourable Chief Minister of Maharashtra Shri. Uddhav Thackeray inaugurated a flyover in the eastern part of the suburbs. In his inaugural speech, he quipped the BMC to smoothen the rough road surface. The BMC swing into action and the surface of the flyover was swiftly re-worked upon. But, instead of smoothening the pre-existing rough surface, the shoddy repair work added to the problem. To top it all off, the BMC added a barrage of speed breakers and rumbler strips on the bridge.
The shoddy repair work combined with a plethora of speed breakers caused long congestions on the Mankhurd-Ghatkopher stretch, ultimately killing the purpose of building the bridge. Moreover, after numerous accidents of motorbikes skidding on the bridge during the rain and the subsequent death of a rider the bridge was closed for traffic.
The construction of the flyover commenced in February 2016 at an approved cost of ₹500 crores. The project was slated to be delivered in January 2019 but was delayed multiple times. The BMC had also made a design change in the flyover by adding a connector to the Deonar dumping ground due to which the construction cost of the flyover was increased to over ₹700 crore. The flyover was expected to bring relief to the traffic on Ghatkopar-Mankhurd Link Road but instead, it added to the existing traffic woes. On a concluding note, the maximum city of Mumbai runs on barely minimum governance, literally.

The Pitru Paksha starts after the Full Moon day, and this day marks the beginning of the waning phase of the Lunar cycle. This event is roughly of 15-day period, and is of great significance. From this day, rituals like Tarpan or Tarpanam and Shradh are carried out to pay respects to dead relatives and ancestors.
It is believed that from the very first day till the last day, the unhappy souls of the deceased return to the Earth to see their family members. So, in order to ensure that the dead attain Moksha, i.e. to get liberation, family members of these souls quench their thirst and satisfy their hunger by performing the Pind Daan, which includes offering food consisting of cooked rice and black sesame seeds. The literal meaning of Pind Daan is the act of satisfying those who no longer exist physically.
For fifteen days, prayers are offered in temples and rituals are performed to help the souls get free from the cycle of birth, life, and death, and attain salvation.
At the same time, the Pitru Paksha is also an important period for people with Pitru Dosha, which means the curse imposed by the ancestors. Hence, in order to ask forgiveness, people perform Shradh rituals and offer food to the crows, who are considered as living beings that represent the dead. It is believed, if the crow eats the offered food, the ancestors are happy and pleased. But, if the crow doesn't eat the offered food and flies away, the ancestors are not happy.
The event of Pitru Paksha is widely observed by Hindus from all over the world, and they perform prayers and rituals in order to gain their ancestors blessings.
