The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.
Gear up and Make the Best Use of this initiative.
Do remember that, “the difference between Ordinary and EXTRA-Ordinary is PRACTICE!!”

Question 3 of 5
3. Question
-
Extreme Nuclear Transients (ENTs), recently in news, are best described as:
Correct
-
Solution: (b)
Explanation
- What are ENTs?
- ENTs (Extreme Nuclear Transients) are a newly identified category of ultra-powerful cosmic explosions.
- They occur when a star drifts too close to a supermassive black hole.
- The intense gravitational pull stretches the star into a thin stream of gas (“spaghettification”), which then emits enormous amounts of electromagnetic radiation.
- Energy Output
- ENTs are considered the biggest explosions since the Big Bang, releasing up to 10 times more energy than previously known record cosmic events like gamma-ray bursts (GRBs).
- How are they different from other cosmic events?
- (a) Ultra-fast radio signals (FRBs): These are short radio bursts from magnetars, not ENTs.
- (c) Solar eruptions: Solar flares/coronal mass ejections release charged particles, but they are much weaker and limited to our Sun.
- (d) Gravitational waves: Produced by mergers of neutron stars or black holes, different from the light-energy explosions of ENTs.
- Observation
- ENTs were detected using data from the Gaia spacecraft and are much rarer than Tidal Disruption Events (TDEs).

Question 4 of 5
4. Question
-
Consider the following statements:
Statement I: The effectiveness of the United Nations in maintaining global peace is often questioned due to the structure of the Security Council.
Statement II: The five permanent members of the UN Security Council (P-5) enjoy veto power, which can block any substantive resolution.
Statement III: Decisions of the International Court of Justice (ICJ) are binding on all UN member states without exception.
Which one of the following is correct in respect of the above statements?
Correct
-
Solution: (c)
Explanation
- Statement I: UN effectiveness is questioned mainly due to veto power in UNSC. This statement is correct
- Statement II: P-5 (US, UK, Russia, China, France) have veto power, blocking action → ✔ Explains Statement I. This statement is correct
Statement III: ICJ decisions are binding only on parties to the case and only if they accepted its jurisdiction; not universally binding on all UN members. This statement is incorrect
Incorrect
