KOMPAS.com – Throughout this May 2021, there are at least 20 astronomical phenomenon will happen.
When confirmed, researchers from the Aeronautics and Space Institute Space Science Center (Eight) Andi Pangerang confirmed the existence of astronomical phenomena throughout this month.
“Astronomical phenomenon for the month of May can be checked at edukasi.sains.lapan.go.id, “said Andi, when contacted Kompas.com, Sunday (2/5/2021) afternoon.
Here are 20 astronomical phenomena that will occur and their dates:
1. Conjunction (Solar) Uranus: May 1
Uranus’s (solar) conjunction is a configuration when Uranus, the Sun and Earth are in a straight line and Jupiter is parallel to the Sun.
The peak of the Jupiter conjunction occurred on May 1 at 02.44 WIB or 03.44 WITA or 04.44 WITA.
The consequence of this phenomenon is that Uranus will no longer be visible in the night sky because it is parallel to the Sun.
2. Moon-Jupiter-Saturn Triple Conjunctions: May 3-6
The Moon will experience triple conjunction with Jupiter and Saturn for four days from May 3 to 6, 2021.
This phenomenon can be witnessed from 2.00 local time until the end of maritime dawn (20-24 minutes before sunrise) from the East-Southeast direction.

3. End of the Phase of the Month of Bandages: May 4
The final bandage phase is one of the phases of the Moon when the configuration between the Sun, Earth and Moon forms a 90 degree right angle and occurs after the Full Moon phase.
The peak of the final bandaging phase occurs at 02.50 WITA or 03.50 WITA or 04.50 WIT.
Thus, the final moonlight can be witnessed when it rises around midnight from the east-southeast direction.
4. Peak Meteor Rain And Aquarid: 6 Mei
The Eta Aquarid Meteor Rain is active from 19 April to 28 May and its peak activity occurs on 6 May at 09.00 WIB or 10.00 WITA or 11.00 WITA.
