Most ancient type of molecule in our universe

Scientists have detected the most ancient type of molecule in our universe- Helium hydride ion– in space for the first time ever.

It was discovered with the help of the GREAT spectrometer aboard SOFIA in the envelope of the planetary nebula NGC 7027.

Despite its importance in the history of the early Universe, HeH+ has so far escaped detection in astrophysical nebulae — cloud of gas and dust in outer space.

Key Facts:

Helium hydride ion (HeH+) was the first molecule that formed when, almost 14 billion years ago, falling temperatures in the young universe allowed recombination of the light elements produced in the Big Bang. At that time, ionized hydrogen and neutral helium atoms reacted to form HeH+.

Key changes to Egypt’s constitution

Egypt is holding a three-day referendum on constitutional amendments that could allow President Abdel Fattah al-Sisi to stay in office until 2030. Parliament this week overwhelmingly approved the proposals, which would also bolster the role of the military and expand the president’s power over judicial appointments.

Critics say they fear that the changes will further limit the space for dissent after a wide-ranging security crackdown.

What are the key changes?

An amendment to Article 140 of the constitution extends the presidential term to six years from four. An outright bar on any president serving more than two terms will change to a bar on serving more than two consecutive terms.

The amendments provide for the creation of a second parliamentary chamber known as the Council of Senators. It would have 180 members, two-thirds elected by the public and the rest appointed by the president.

Naval fleet reviews

China is planning to observe an international fleet review on April 23 at Qingdao to mark the 70th anniversary of founding its naval forces. Nearly 60 countries are sending naval delegations for the fleet review, including India (INS Kolkata and INS Shakti), Japan, South Korea and others. The United States declined to be part of the show.

What is it?

Naval fleet reviews intend to not only gather forces from other countries but make a statement about a nation coming of age in this domain. Such shows are intended to enhance confidence building. They as well seek to legitimize the official stance on various “core interests” but also seek consent and respect from other navies. These go a long way in ushering conventional deterrence in the region. Domestically, fleet reviews suggest to the coalescing of forces in supporting maritime agenda of the nation and the leadership.
